PERFORMANCE CHARACTERISTICS
1.
Operating Temperature: Capacitors are designed to
operate over the temperature range of - 55°C to + 85°C.
1.1
Capacitors may be operated to + 125°C with voltage
derating to two-thirds the + 85°C rating.

DC Working Voltage: The DC working voltage is the
maximum operating voltage for continuous duty at the
rated temperature.
3.
Surge Voltage: The surge DC rating is the maximum
voltage to which the capacitors may be subjected
under any conditions, including transients and peak
ripple at the highest line voltage.
3.2
Surge Voltage Test: Capacitors shall withstand the
surge voltage applied in series with a 33 ohm ± 5%
resistor at the rate of one-half minute on, one-half
minute off, at + 85°C, for 1000 successive test cycles.
Following the surge voltage test, the dissipation factor

4.
Capacitance Tolerance: The capacitance of all
capacitors shall be within the specified tolerance
limits of the normal rating.
4.1
Capacitance measurements shall be made by means
of polarized capacitance bridge. The polarizing
voltage shall be of such magnitude that there shall be
no reversal of polarity due to the AC component.
The maximum voltage applied to capacitors during
measurement shall be 2 volts rms at 120 Hz at
+ 25°C. If the AC voltage applied is less than onehalf volt rms, no DC bias is required. Accuracy of the
bridge shall be within ± 2%.
5.
Capacitance Change With Temperature: The
capacitance change with temperature shall not
exceed the following percentage of the capacitance
measured at + 25°C:

6.
Dissipation Factor: The dissipation factor,
determined from the expression 2πfRC, shall not
exceed values listed in the Standard Ratings Table.

Measurements shall be made by the bridge method
at, or referred to, a frequency of 120 Hz and a
temperature of + 25°C.

change shall not exceed ± 10%; the leakage
current shall not exceed 125% of the initial
requirement.
PERFORMANCE CHARACTERISTICS (Continued)
7.
Leakage Current: Capacitors shall be stabilized at
the rated temperature for 30 minutes. Rated voltage
shall be applied to capacitors for 5 minutes using a
steady source of power (such as a regulated power
supply) with a 1000 ohm resistor connected in series
with the capacitor under test to limit the charging
current. Leakage current shall then be measured.
Note that the leakage current varies with temperature and
applied voltage. See graph below for the appropriate

heating effects which differ from those shown. It is
important that the equivalent Irms value be
established when calculating permissible operating
levels. (Power Dissipation calculated using + 25°C

in the table in Paragraph Number 5 (Power

RESR = The capacitor Equivalent Series Resistance

equal to 10% of the DC rating at + 25°C, 5% of the
DC rating at + 85°C and 1% of the DC rating at

7.1
Solder Paste: The recommended thickness of the
solder paste after application is .007" ± .001"
[.178mm ± .025mm]. Care should be exercised in
selecting the solder paste. The metal purity should
be as high as practical. The flux (in the paste) must
be active enough to remove the oxides formed on the
metallization prior to the exposure to soldering
heat. In practice this can be aided by extending
the solder preheat time at temperatures below the
liquidous state of the solder.
7.2
Soldering: Capacitors can be attached by
conventional soldering techniques - vapor phase,
infrared reflow, wave soldering and hot plate
methods. The Soldering Profile chart shows
maximum recommended time/temperature
conditions for soldering. Attachment with a
soldering iron is not recommended due to the
difficulty of controlling temperature and time at
temperature.
8.
Cleaning (Flux Removal) After Soldering: The
CWR11 is compatible with all commonly used
solvents such as TES, TMS, Prelete, Chlorethane,
Terpene and aqueous cleaning media. However,
CFC/ODS products are not used in the production of
these devices and are not recommended. Solvents
containing methylene chloride or other epoxy solvents
should be avoided since these will attack the epoxy
encapsulation material.
8.1
When using ultrasonic cleaning, the board may
resonate if the output power is too high. This vibration
can cause cracking or a decrease in the adherence
of the termination. DO NOT EXCEED 9W/l @ 40kHz
for 2 minutes.
Temperature Derating: If these capacitors are to be
operated at temperatures above + 25°C, the
permissible rms ripple current or voltage shall be
calculated using the derating factors as shown:

Recommended Mounting Pad Geometries: Proper mounting pad geometries are essential for successful solder
connections. These dimensions are highly process sensitive and should be designed to minimize component rework
due to unacceptable solder joints. The dimensional configurations shown are the recommended pad geometries for both
wave and reflow soldering techniques. These dimensions are intended to be a starting point for circuit board designers
and may be fine tuned if necessary based upon the peculiarities of the soldering process and/or circuit board design.
