Introduction to NEC TOKIN E.M. Devices
Since NEC industrialized telephone relays in Japan more than a half century ago, many technological innovations have taken place in its electromechanical devices (E.M. devices).
NEC’s relays were designed and manufactured always on the basis of the newest technology that
the company develops. Their high reliability and advanced features assure the high reliability and
high performance of your products.
NEC divided and transferred its business of manufacturing and sale of relays to Tokin, as of April
1, 2002. Then Tokin Corporation changed its corporate name to “NEC TOKIN Corporation,” which
has charge of electronic components business within the NEC Group.

NOTES ON CORRECT USE
This section provides notes on correctly using the miniature relay. Be sure to read this before using the relay.
Proper functioning of the miniature relay requires appropriate circuit design, mounting and evaluation according
to the purpose of use.
Note that the responsibility for accidents caused by improper circuit design, mounting or evaluation falls on you
and we cannot be responsible for them.
1. GENERAL
(1) Never allow the contact load to exceed the maximum ratings; otherwise, the lifetime of the relay will be dramatically
shortened.
The lifetime specified in the catalog is for certain load conditions, and other factors must be taken into consideration in
actual circuits. Therefore, an accurate lifetime must be measured in the actual circuit.
The two tables below show load current range guidelines.

VERY GOOD
• Since different contact
phenomena occur
depending on the
contact load, it is
necessary to select
the correct contacts.
(2) When using the relay with a high current or high capacitance load, an inrush current may cause contact dislocation or
deposition; therefore check the feasibility of use in the actual circuit.
(3) Be sure to use the relay at an ambient temperature within the maximum ratings; otherwise, the life of the relay will be
radically shortened. If use outside the specified temperature range in unavoidable, consult NEC TOKIN.
(4) With a relay whose coil polarity is specified in its internal circuit diagram, apply the polarity of the rated voltage as specified. Note that when a rippled DC power source is used, abnormalities such as beat in the coil may occur.
(5) Exercise care when handling the relay so as not to apply shock to it or drop it.
(6) The flow soldering conditions are for 5 to 10 seconds at 250 °C.
(7) When cleaning, use alcohol, or a water-based solvent. Avoid using ultrasonic cleaning.

2. NOTES ON CONTACT LOAD
(1) Minimum load
Use the relay at a voltage and current higher than the minimum load; otherwise, the contact resistance will increase and the
signal cannot be correctly transmitted. This is because stabilization of the contact surface (electrically and mechanically
eliminating minute substances generated on the contact surface) by opening/closing the contacts with the minimum load
probably will not occur.
In addition, even if the load is within the maximum ratings, care is required to ensure that the current does not drop below the
minimum load after opening/closing the contacts.
(2) Contact protection circuit
By providing a protection circuit that suppresses transient current and voltage applied to the contacts when the contacts are
opened or closed, the switching life of a relay can be improved.
It is important to select a correct protection circuit suited to the load.
➀ General notes
(a) It is necessary to place the protection circuit close to the contacts. In principle, place it on the same printed circuit
board as that for the contacts (within a distance of several tens of centimeters).
(b) It is important to confirm the effectiveness of the protection circuit in the actual circuit. In some cases, it is also necessary
to conduct lifetime tests using an appropriate equivalent circuit.
➁ Examples of contact protection circuits
(a) Inductive load
With an inductive load, when the contacts are opened to break the circuit, a counter electromotive force as shown in
Fig. 1 is generated, causing an electric discharge between the contacts. This discharge energy accelerates metal
dislocation and wear on the contact surface. A protection circuit is therefore necessary to absorb this counter electromotive force. Table 1 shows guideline circuit examples and circuit constants. Never use a connection with a capacitor
only as shown in Table 2.

(b) Lamp loads (inrush current), etc.
Some loads, such as halogen lamps, have a low initial resistance so that an inrush current 10 times as high as the
steady-state current may flow through the relay on power application. A high inrush current may also flow when the
relay is used to switch loads such as motors and capacitors. In these cases, a current-limiting resistor is connected
to the contacts in series in order to keep the inrush current to within the maximum rated value (refer to Fig. 2).

(c) Stray line capacitance
When the stray line capacitance is large, the inrush current that is generated due to the stray line capacitance poses
a problem. As shown in Fig.3, the electric charge on the line capacitance is discharged directly through the contacts
when the contacts are closed. The smaller the wiring cable characteristic impedance and the longer the cable, the
greater wear on the contacts.
It is necessary to connect a current-limiting resistor or surge suppresser in series with the contacts as a protection
circuit to suppress the inrush current.

3. NOTES ON DRIVING RELAYS
(1) Temperature characteristics
If the relay is used at an ambient temperature exceeding the operating temperature range, the performance of the relay may
be degraded and the life may be dramatically shortened.
➀ It is possible to use the relay at the rated coil voltage within the operating temperature range. Note, however, that at the
upper limit of the operating temperature range the permissible voltage on the coil may be restricted, and must be confirmed
before the relay is used.
➁ The must operate voltage, must release voltage, operate time and release time change with the ambient temperature. Refer
to Technical Documents to confirm that the relay operates normally at a particular operating temperature.Fig.4 shows an

(2) Maximum applied voltage
The maximum applied voltage of the relay coil changes with the ambient temperature. The difference between the permissible
temperature specified by relay design and the operating temperature is the permissible temperature rise (the self-heat
temperature, i.e., the applied-voltage-dependent portion).
Refer to the coil voltage vs. temperature derating characteristics in the Technical Documents for this value. Fig. 5 shows an
example.
The permissible temperature of the relay is determined mainly by the coil wire materials and the permissible temperature of
the plastic materials used. In the case of the NEC TOKIN miniature signal relay, it is set at 120 °C in the standard specification.
The larger the coil applied voltage, the shorter the operate time becomes. Note, however, that bounces in the make contacts

(ratio to rated voltage) (%)
also become larger, increasing the contact opening/closing frequency, which may affect the life of the contacts.

(3) Hot start
When the temperature of the relay has risen due to heat generated by the voltage applied to the coil, the relay may not
operate even if the coil is energized again immediately after it has been once deenergized. This is because an increase in
the coil resistance due to heat in the relay causes the current to fall even though the applied voltage remains constant.
This reenergizing state is called a hot start. This problem occurs especially when the operating temperature is high and a
voltage lower than the relay rated voltage is applied. It is necessary to refer to Technical Documents to know in advance the
must operate voltage at the time of a hot start in order to prevent this malfunction.
(4) Non-must operate and holding voltages
In some circuits, the relay must not operate at a certain voltage or release at a certain voltage. In such cases, contact

(6) Latching relay drive circuit
➀ Since the relay coil has an inductive impedance, a counter electromotive force is generated when the circuit is opened.
This voltage may damage the relay driver transistor, and therefore a diode is connected in parallel with each coil. With
a single coil latching type relay, however, a diode cannot be used because the current direction of the coil is inverted.
Therefore, when a single coil latching type relay is used, select a transistor with sufficient reverse breakdown voltage.
➁ A latching relay is driven by a pulsating coil voltage. The pulse width of this drive voltage must be 10 ms or wider. If the
pulse is too short, the relay may not operate.
➂ Apply a voltage to the coil in the polarity specified by the internal connection diagram of the relay. With a double coil
latching type relay, do not apply voltage in a manner that both the set and reset coils are energized at the same time.
(Refer to Fig. 8.)

Reset pulse
Fig.8 Drive Circuit of Latching Relay (Example of Double Coil Latching Type)
➃ A latching relay is factory-set to the reset state for shipment. However, it may be set while being transported due to
vibration or shock. Make sure that the relay is reset when its application system starts operating. When the relay is
employed in a portable system, the circuit must be designed so that the relay is reset at the beginning of operation of
the system because the relay may be set by unexpected vibration or shock.
➄ When configuring a self-holding circuit that uses the self-break contacts of the relay, note that the coil drive circuit is
disconnected by the self-contacts, causing troubles such as self-oscillation.
(7) Connection of coil diode
In the case of loads, such as solenoid and electromagnetic clutches, that produce large discharge energy when the contacts
are opened, connect a Zener diode with the drive transistor.
Particularly when the diode is connected in parallel with the coil, the current in the coil diminishes gradually when the relay is
released, and thus may slow down opening of the contacts, intensifying wear on the contacts.
(8) Opening/closing frequency
If the contacts are opened/closed frequently with a high current load, repeated electric discharges may cause contact metal
deposition or damage to the contact spring. When using the relay with a high current load with frequent opening/closing of
the contacts, consult NEC TOKIN.
(9) Long continuous energizing of coil
If the coil is energized continuously for a long time, the coil temperature may rise, promoting generation of organic gas inside
the relay, which is likely to cause trouble in the contacts. When using a circuit requiring constant operation, consider the
possibility of using a latching relay that does not need continuous energizing of the coil.

(10)Instantaneous voltage drop of circuit
When the same power source is used for the relay drive circuit and the load circuit in a circuit such as a lamp load circuit
where an inrush current flows, the moment the contacts are closed the source voltage may drop if the power source
capacitance is small. In this case, the relay may be released or an oscillation phenomenon where the relay repeatedly
releases and operates may occur.
Add power source capacitance or a smoothing circuit to prevent this phenomenon.
4. NOTES ON OPERATING ENVIRONMENTS
(1) Ambient temperature
Ensure that the ambient temperature of the relay mounted on the device is within the “operating temperature range” in the
catalog. Use of the relay at a temperature outside this range may adversely affect insulation or contact performance. For
the relationship between the ambient temperature and relay drive conditions, refer to 3. Notes on Driving Relays.
(2) Humidity
Use of a sealed type relay in a high humidity (RH85 % or higher) environment for a long time may introduce moisture inside
the relay. This moisture may combine with NOx or SOx generated by glow discharges to produce nitric acid or sulfuric
acid. In this case, the acid produced may corrode the metal that forms the relay, causing operation troubles in the relay. If
use of the relay in such a high humidity environment is unavoidable, consult NEC TOKIN in advance.
(3) Atmosphere
Use of a relay in an atmosphere with a high concentration of sulfur gases (H2S, SO2), nitric acid gas (HNO3), ammonia
(NH3), silicon vaporization gas, etc., may cause imperfect contacts and other functional trouble. Avoid use of the relay in
such an atmosphere. If it is unavoidable, use a sealed type relay.
(4) Atmospheric pressure
A sealed type relay maintains constant sealability under normal pressures (810 to 1200 hpa). However, if it is used under
other pressure conditions, its sealability may be destroyed or the relay may be deformed, causing functional trouble. Be
sure to use the relay under normal pressure conditions.
(5) Vibration and shock
The vibration resistance and shock resistance of a relay are as shown in the catalog and use of the relay under conditions other
than those specified may cause malfunctions or damage.
Be sure to use the relay within those vibration and shock conditions.
Even before the relay is used, repeated excessive vibration or shock load may cause malfunctioning of the relay, by causing
metal deposition on the contacts and other functional trouble. Malfunctions due to vibration or shock during operation
may cause considerable damage or wear of the contacts.
Note that operation of a snap switch mounted close to the relay or shock by operation of an electromagnet may cause
malfunctioning.
(6) Influence of magnetic fields
The magnetic circuit of an NEC TOKIN miniature signal relay is constructed so that the relay does not easily malfunction due
to influence of external magnetic fields. However, under the influence of magnetic flux leaking from a transformer, speaker,
or magnet placed in the vicinity of the relay, the must operate voltage, must release voltage, operate time, release time and
other dynamic characteristics may change.
In applications where these characteristics changes pose problems, it is necessary to take measures such as magnetic
shielding. Also, when many make them miniature signal relays are closely located, the magnetic flux leaking from those
relays may make them interfere with each other, causing changes in the must operate voltage, must release voltage,
operate time, release time and other dynamic characteristics. Fig. 9 shows examples of the mounting, magnetization, and
change in the must operate voltage of signal relays in the EA2 series. In applications where these characteristics changes
pose a problem, it is necessary to reduce the mounting density.

5. INFLUENCE OF RELAY OPERATION ON SURROUNDINGS
(1) Electromagnetic noise
Switching the relay coil generates a high electromotive force due to induction. In general, a surge suppression circuit is
connected in parallel with the relay coil to suppress generation of this electromotive force. However, if this suppression
circuit is not appropriate, electronic circuits such as microcontrollers may malfunction due to the surge generated. Add an
appropriate absorption circuit to prevent electronic circuits from malfunctioning due to the surge generated.
(2) Arc discharge
Connecting/disconnecting a high current at the relay contacts generates an arc discharge. This discharge may cause electronic
circuits such as microcontrollers to malfunction and therefore it is necessary to take appropriate measures.
(3) Generation of leakage magnetic flux
Leakage magnetic flux exists in the vicinity of the relay in the magnetized state. Mounting a magnetic sensor, etc. close to the
relay may cause malfunctioning.
6. NOTES ON MOUNTING
(1) Design of printed circuit boards
➀ If an electronic circuit such as a microcontroller is placed close to a relay, noise generated by the relay may cause
malfunctioning.
➁ When designing patterns keep to the shortest possible distance in wiring.
➂ For the printed circuit board on which a relay is mounted, use a board of 1 mm or more in thickness. If the printed circuit
board is not thick enough, it may be subject to warpage which will add tension to the relay, causing variations in the relay
characteristics. Because a flexible printed circuit board is particularly thin, it is necessary to solder near the root of the relay
pins. Since preliminary soldering of the pin root part is often insufficient, its solder is likely to become loose.
➃
If a thermal cycle is applied to the soldered part, cracks may be generated in it. Special care is required for the relay location,
base material and through hole shape.

(2) Relay mounting position
The vibration resistance and shock resistance of a relay are greatly affected by its mounting position. It is particularly
important to select the mounting position to prevent the break contacts from being instantaneously cut due to vibration
and shock. The vibration resistance and shock resistance are at a minimum when the direction of vibration and shock applied
to the relay matches the operation direction of the armature (mobile iron piece) and contacts. Therefore, if it is
possible to anticipate the direction of vibration or shocks, mount the relay so that the direction in which vibration or shocks
are applied is perpendicular to the direction of the relay armature operation. Fig. 10 shows the direction of relay armature
operation.

(3) Notes on mounting
➀ Chucking
When a relay is mounted using an automatic machine, note that application of an excessive external force to the cover
at the time of chucking or insertion of the relay may damage or change the characteristics of the cover.
➁ Temporary securing to printed circuit board
Avoid bending the pins to temporarily secure the relay to the printed circuit board. (Refer to Fig. 11.) Bending the pins
may degrade sealability or adversely influence the internal mechanism. Pin bending may be allowed under certain
conditions in the case of miniature signal relays. Contact NEC TOKIN for details.

➂ Application of soldering flux
For an unsealed type relay, do not directly apply soldering flux to the relay.
➃ Soldering work
The following conditions are recommended for soldering a relay onto a printed circuit board.
(a) Automatic soldering: Flow solder is recommended.
<Recommended conditions> *Preheating: 100 °C max. 1 min. max.
*Solder temperature: 260 °C max.
*Solder time: 5 to 10 seconds
(b) Manual soldering (by soldering iron):
<Recommended conditions>
*Solder temperature: 350 °C max.
*Solder time: 2 to 3 seconds
Ventilation immediately after soldering is completed is recommended.
Avoid immersing the board in cleaning solvent immediately after soldering; otherwise thermal shock may be applied
to it.
➄ Pin cutting after soldering
Do not cut the pins of the relay with a revolving blade or an ultrasonic cutter, because vibration that is applied to the relay
during the cutting may change the relay characteristics.
7. NOTES ON CLEANING
(1) Cleaning solvent
Use of alcohol or water-based cleaning solvents is recommended. Never use thinner or benzene because these solvents
may damage the relay housing. A sealed type relay can be immerse-cleaned because solvent does not penetrate inside the
relay.
(2) Avoid ultrasonic cleaning.
Ultrasonic cleaning may cause a break in the coil wire or sticking of the contacts due to the energy of vibration.
8. NOTES ON HANDLING RELAYS
(1) Use of magazine case stoppers
Relays are packaged in magazine cases for shipment.
When some relays are taken out from the case and space is freed inside the case, be sure to secure the relays in the case
with a stopper. If the relays are not well secured, vibration during transportation may cause contact problems.

(2) Do not use relays that have been dropped.
If an individual relay product falls from the work table, etc. a shock of 1000 G or more is applied to the relay and its functions
may be destroyed. Even if the shock is apparently weak, confirm that there is no abnormality before using the relay.

9. NOTES ON USING SMT RELAYS
(1) Mounting pads
Determine the dimensions of the mounting pads on the printed circuit board taking into consideration such factors as
solderability and insulation in order to accommodate the mounting accuracy of the automatic mounter. Use the dimensions of the mounting pads in the catalog.
(2) Solder reflow
The SMT relay is highly resistant to heat. However, solder the relay under the correct temperature conditions so that the
full performance of the relay can be realized. The IRS (infrared ray reflow soldering) and VPS (vapor phase soldering: reflow
by using latent heat of organic solvent) methods are recommended.
In addition, air reflow soldering may also be used. Whichever soldering method is used, be sure to confirm the temperature conditions for soldering and the influence of soldering on the relay in advance before setting work standards.
(3) Storage
The sealability of a surface-mount relay may be lost if the relay absorbs moisture and is then heated during soldering .
Please use relays within 12 months form the data of delivery. (Storage conditions : 30 degree C/60% RH)
