PERFORMANCE CHARACTERISTICS (Continued)
10. Humidity test: After 56 days (1350 hours) at + 40 °C,
90 to 95 % of relative humidity (per IEC 68-2-3) with
no voltage applied, capacitors shall meet the
requirements in table 7 below.
Table 7
Table 8
Typical values of charge-discharge current (per above test
conditions).
12. Insulation test: For capacitors with insulating
sleeves, a DC voltage of 100 volts shall be applied for
one minute between the case of the capacitor and a
metal “V” block in intimate contact with the insulating
sleeve. The insulating resistance measured in these
conditions shall be at least 100 megohms.
13. Lead pull test: Leads shall withstand the following
test (IEC 68 - 2 - 2):
•Tensile stress of 5N (cases A and B) or 10N
(cases C and D) for 10 seconds in any direction
•One bend in each direction
•Two consecutive rotations of 180°
GUIDE TO APPLICATION
1. A-C Ripple Current: The maximum allowable ripple
current shall be determined from the formula:
where,
P = Power Dissipation in Watts at + 25 °C as
given below
RESR = The capacitor Equivalent Series
Resistance at the specified frequency.
2. A-C Ripple Voltage: The maximum allowable ripple
voltage shall be determined from the formula:
where,
Z = The capacitor Impedance at the specified
frequency.
The calculations are summarized on the graphs page
7 giving the maximum available ripple voltage as a
function of frequency.
However, the sum of the peak AC voltage plus the DC
voltage shall not exceed the rated DC voltage at
+ 85 °C of the capacitor. The sum of the negative peak
AC voltage plus the DC voltage shall not allow a
voltage reversal exceeding 15 % of the rated DC
voltage.
3. AC Ripple Current or Voltage Derating Factor: 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
in the table below:
4. Power Dissipation: Power dissipation will be affected
by the heat sinking capability of the mounting surface.
Non-sinusoidial ripple current may produce heating
effects which differ from those shown in the following
table. It is important that the equivalent Irms value be
established when calculating permissible operating
levels.
