7.CAUTIONS
(1) Cautions
· The devices are UV light LEDs.
The LED during operation radiates intense UV light,
which precautions must be taken to prevent looking directly at the UV light with unaided eyes.
Do not look directly into the UV light or look through the optical system.
When there is a possibility
to receive the reflection of light, protect by using the UV light protective glasses so that light should not
catch one’s eye directly.
· Put the caution label on the cardboard box.

CLASS 1M LED PRODUCT
(2) Lead Forming
· When forming leads, the leads should be bent at a point at least 3mm from the base of the lead.
Do not use the base of the leadframe as a fulcrum during lead forming.
· Lead forming should be done before soldering.
· Do not apply any bending stress to the base of the lead. The stress to the base may damage the LED’s
characteristics or it may break the LEDs.
· When mounting the LEDs onto a printed circuit board, the holes on the circuit board should be exactly
aligned with the leads of the LEDs. If the LEDs are mounted with stress at the leads, it causes
deterioration of the lead and this will degrade the LEDs.
(3) Storage
· The LEDs should be stored at 30°C or less and 70%RH or less after being shipped from Nichia and
the storage life limits are 3 months.
If the LEDs are stored for 3 months or more, they can be stored
for a year in a sealed container with a nitrogen atmosphere and moisture absorbent material.
· Nichia LED leads are gold plated Iron alloy. The gold surface may be affected by environments which
contain corrosive substances. Please avoid conditions which may cause the LED to corrode,
tarnish or discolor. This corrosion or discoloration may cause difficulty during soldering operations.
It is recommended that the LEDs be used as soon as possible.
· Please avoid rapid transitions in ambient temperature, especially, in high humidity environments where
condensation can occur.

<Cat.No.090427>
(4) Recommended circuit
· In designing a circuit, the current through each LED must not exceed the absolute maximum rating
specified for each LED. It is recommended to use Circuit B which regulates the current flowing
through each LED. In the meanwhile, when driving LEDs with a constant voltage in Circuit A, the
current through the LEDs may vary due to the variation in forward voltage (VF) of the LEDs. In the
worst case, some LED may be subjected to stresses in excess of the absolute maximum rating.
(B)
(A)
...
...
· This product should be operated in forward bias. A driving circuit must be designed so that the product
is not subjected to either forward or reverse voltage while it is off. In particular, if a reverse voltage is
continuously applied to the product, such operation can cause migration resulting in LED damage.
(5) Static Electricity
· Static electricity or surge voltage damages the LEDs.
It is recommended that a wrist band or an anti-electrostatic glove be used when handling the LEDs.
· All devices, equipment and machinery must be properly grounded. It is recommended that precautions
be taken against surge voltage to the equipment that mounts LEDs.
· When inspecting the final products in which LEDs were assembled, it is recommended to check
whether the assembled LEDs are damaged by static electricity or not.
It is easy to find static-damaged
The LEDs
LEDs by a light-on test or a VF test at a lower current (below 1mA is recommended).
should be used the light detector etc. when testing the light-on. Do not stare into the LEDs when testing.
· Damaged LEDs will show some unusual characteristics such as the forward voltage becomes lower,
or the LEDs do not light at the low current.
Criteria : (VF > 2.0V at IF=0.5mA)

(6) Soldering Conditions
· Solder the LED no closer than 3mm from the base of the lead.
· Recommended soldering conditions
Dip Soldering
Hand Soldering
Pre-Heat
120°C Max.
Temperature
350°C Max.
Pre-Heat Time
60 seconds Max.
Soldering Time
3 seconds Max.
Solder Bath

Position
No closer than 3 mm from the
base of the lead.
Temperature
Dipping Time
10 seconds Max.
Dipping Position
No lower than 3 mm from the
base of the lead.
· Although the recommended soldering conditions are specified in the above table, dip or hand
soldering at the lowest possible temperature is desirable for the LEDs.
· A rapid-rate process is not recommended for cooling the LEDs down from the peak temperature.
· Dip soldering should not be done more than one time.
· Hand soldering should not be done more than one time.
· Do not apply any stress to the lead particularly when heated.
· The LEDs must not be repositioned after soldering.
· After soldering the LEDs, the lead should be protected from mechanical shock or vibration until
the LEDs return to room temperature.
· Direct soldering onto a PC board should be avoided.
Mechanical stress to the resin may be caused
from warping of the PC board or from the clinching and cutting of the leadframes.
When it is
absolutely necessary, the LEDs may be mounted in this fashion but the customer will assume
responsibility for any problems.
Direct soldering should only be done after testing has confirmed that
no damage, such as wire bond failure or resin deterioration, will occur.
Nichia’s LEDs should not be
soldered directly to double sided PC boards because the heat will deteriorate the epoxy resin.
· When it is necessary to clamp the LEDs to prevent soldering failure, it is important to minimize
the mechanical stress on the LEDs.
· Cut the LED leads at room temperature.
Cutting the leads at high temperatures may
cause failure of the LEDs.
(7) Heat Generation
· Thermal design of the end product is of paramount importance.
Please consider the heat generation
of the LED when making the system design. The coefficient of temperature increase per input
electric power is affected by the thermal resistance of the circuit board and density of LED placement
on the board, as well as other components. It is necessary to avoid intense heat generation and operate
within the maximum ratings given in this specification.
· The operating current should be decided after considering the ambient maximum temperature of LEDs.

<Cat.No.090427>
(8) Cleaning
· It is recommended that isopropyl alcohol be used as a solvent for cleaning the LEDs.
When using
other solvents, it should be confirmed beforehand whether the solvents will dissolve the glass or not.
Freon solvents should not be used to clean the LEDs because of worldwide regulations.
· Do not clean the LEDs by the ultrasonic.
When it is absolutely necessary, the influence of ultrasonic
cleaning on the LEDs depends on factors such as ultrasonic power and the assembled condition.
Before cleaning, a pre-test should be done to confirm whether any damage to the LEDs will occur.
(9) Safety Guideline for Human Eyes
· The International Electrical Commission (IEC) published in 2006 IEC 62471:2006 Photobiological
safety of lamps and lamp systems which includes LEDs within its scope. Meanwhile LEDs were
removed from the scope of the IEC 60825-1:2007 laser safety standard, the 2001 edition of which
included LED sources within its scope. However, keep in mind that some countries and regions have
adopted standards based on the IEC laser safety standard IEC 60825-1:2001 which includes LEDs
within its scope.
Following IEC 62471:2006, most of Nichia LEDs can be classified as belonging to either Exempt
Group or Risk Group 1. Optical characteristics of a LED such as radiant flux, spectrum and light
distribution are factors that affect the risk group determination of the LED. Especially a high-power
LED, that emits light containing blue wavelengths, may be in Risk Group 2.
Great care should be taken when viewing directly the LED driven at high current or the LED with
optical instruments, which may greatly increase the hazard to your eyes.
(10) Others
· NSHU551B complies with RoHS Directive.
· This LED also emits visible light. Please take notice of visible light spectrum, in case you use this LED
as light source of sensors etc.
· The LEDs described in this brochure are intended to be used for ordinary electronic equipment (such
as office equipment, communications equipment, measurement instruments and household appliances).
Consult Nichia’s sales staff in advance for information on the applications in which exceptional quality
and reliability are required, particularly when the failure or malfunction of the LEDs may directly
jeopardize life or health (such as for airplanes, aerospace, submersible repeaters, nuclear reactor
control systems, automobiles, traffic control equipment, life support systems and safety devices).
· The customer shall not reverse engineer by disassembling or analysis of the LEDs without having prior
written consent from Nichia.
When defective LEDs are found, the customer shall inform Nichia
directly before disassembling or analysis.
· The formal specifications must be exchanged and signed by both parties before large volume purchase begins.
· The appearance and specifications of the product may be modified for improvement without notice.
