13.1 Capacitors shall be subjected to temperature
cycling at 90 % to 98 % relative humidity, in a test
chamber constructed of non-reactive materials
(non-resiniferous and containing no formaldehyde or
phenol). Steam or distilled, demineralized or
deionized water having a pH value between 6.0 and
7.2 at + 23 °C shall be used to obtain the required
humidity. No rust, corrosive contaminants or
dripping condensate shall be imposed on test
specimens.
13.1.1 Capacitors shall be mounted by their normal
mounting means in a normal mounting position and
placed in a test chamber so that uniform and
thorough exposure is obtained.
13.1.2 No conditioning or initial measurements will be
performed prior to temperature cycling. Polarization

13.1.3 Capacitors shall be subjected to temperature cycling
from + 25 °C to + 65 °C to + 25 °C (+ 10 °C, - 2 °C)

humidity, for 20 cycles.
13.1.4 Temperature cycling shall be stopped after an even
number of cycles 5 times during the first 18 cycles,
and the capacitor shall be alloweed to stabilize at

of 1 min, for 15 cycles.
13.1.7 Capacitors shall then be returned to temperature/
humidity cycling.
13.2 After completion of temperature cycling, capacitors
shall be removed from the test chamber and
stabilized at room temperature for 2 h to 6 h.
13.3 Capacitors shall show no evidence of harmful or
extensive corrosion, obliteration or marking or other
visible damage.

+ 125 °C (+ 3 °C, - 0 °C) for 30 min, then
+ 25 °C (+ 10 °C, - 5 °C) for 5 min, for 5 cycles.
15.3 Between 4 h and 24 h after temperature cycling,
capacitors shall be subjected to immersion in a bath
of fresh tap water with the non-corrosive dye
Rhodamine B added, at + 65 °C (+ 5 °C, - 0 °C) for
15 min, then, within 3 s, immersed in a saturated
solution of sodium chloride and water with
Rhodamine B added, at a temperature of + 25 °C
(+ 10 °C, - 5 °C) for 15 min, for 2 cycles.
15.3.1 Capacitors shall be thoroughly rinsed and wiped or
air-blasted dry immediately upon removal from
immersion cycling.
15.4 Capacitors shall show no evidence of harmful or
extensive corrosion, obliteration of marking or other
visible damage.
15.5 Following the thermal shock immersion cycling test,
capacitors shall meet the original requirements for
leakage current and dissipation factor; capacitance
change shall not exceed ± 5 % of the original
measured value.
15.6 Capacitors shall be opened and examined. There
shall be no evidence of dye penetration.
16. Reduced Pressure Test:
16.1 Capacitors shall be stabilized at a reduced pressure

100 000 feet [30.480 m], for a period of 5 min.
16.2 Rated DC voltage shall be applied for 1 min.
16.3 Capacitors shall not flash over nor shall end seals be
damaged.
16.4 Following the reduced pressure test, the
capacitance, equivalent series resistance and
leakage current shall meet the original requirements.
17. Lead Pull Test: Leads shall withstand a tensile
stress of 3 pounds (1.4 kg) applied in any direction for
30 s.
18. Marking: Capacitors shall be marked with Sprague
or (2); the type number 550D; rated capacitance and
tolerance, rated DC working voltage and the
standard EIA date code.
18.1 Capacitors shall be marked on one end with a plus
sign (+) to identify the positive terminal.
18.2 Vishay Sprague reserves the right to furnish
capacitors of higher working voltages than those
ordered, where the physical size of the higher voltage
units is identical to that of the units ordered.

GUIDE TO APPLICATION
1. AC Ripple Current: The maximum allowable ripple
current shall be determined from the formula:
where,
P = Power Dissipation in W at + 25 °C as given in
the table in paragraph number 5
(Power Dissipation)
RESR = The capacitor Equivalent Series Resistance
at the specified frequency
2. AC Ripple Voltage: The maximum allowable ripple
voltage shall be determined from the formula:
or, from the formula:
where,
P = Power Dissipation in W at + 25 °C as given
in the table in paragraph number 5
(Power Dissipation).
RESR = The capacitor Equivalent Series Resistance
at the specified frequency.
Z = The capacitor Impedance at the specified
frequency.
2.1 The sum of the peak AC voltage plus the DC voltage
shall not exceed the DC voltage rating of the
capacitor.
2.2 The sum of the negative peak AC voltage plus the
applied DC voltage shall not allow a voltage reversal
exceeding 15 % of the DC working voltage at
+ 25 °C.
3. Reverse Voltage: These capacitors are capable of
withstanding peak voltages in the reverse direction
equal to 15 % of the DC rating at + 25 °C, 10 % of
the DC rating at + 55 °C; 5 % of the DC rating at
+ 85 °C.
4. 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:
5. Power Dissipation: The figures shown relate to an
approximate + 20 °C rise in case temperature
measured in free air. Power dissipation will be
affected by the heat sinking capability of the
mounting surface. Non-sinusoidal ripple current may
produce heating effects which differ from those
shown. It is important that the equivalent Irms value
be established when calculating permissable
operating levels.
