Sensitivity to Frequency and Temperature:

Ripple current ratings are specified at an ambient temperature
of 85ºC in circulating air, using the 25ºC values of E.S.R.

The maximum allowable ripple current may be adjusted for
frequencies other than 120 Hz and temperatures other than
85ºC using the tables below.

APPLIED VOLTAGE

The combined Peak AC Voltage and DC Voltage shall not exceed the DC Voltage Rating
of the capacitor, or the reverse DC Voltage Rating of the capacitor.

REVERSE VOLTAGE

Unless otherwise spec ified, the maximum permissible reverse voltage rating for all
aluminum Electrolytic Capacitors is 1.5 volts.

SHELF LIFE

Aluminum Electrolytic Capacitors which have been stored for extended periods or in
elevated temperatures undergo dielectric deterioration causing DC Leakage currents to
increase beyond allowable levels. Sustained elevated Leakage currents cause
decreased service life due to higher device operating temperatures. Use of capacitors
exhibiting excessive leakage currents may cause premature activation of the pressure
sensitive safety vent, or total dielectric failure.

The normal shelf life expectancy for these capacitors is described by Charts APC2 & APC3
on page 70. Units suspected of exceeding the “maximum Shelf Life” line in this chart,
should be discarded and replaced. It is recommended that units be reformed only once
to reduce the DC Leakage current to specification levels.
