TEST INFORMATION
Robustness of leads
Tensile strength of leads (Ua) (load in lead axis direction)
Lead diameter 0.5 mm, 0.6 mm and 0.8 mm:
Load 10 N, 10 s.
Bending (Ub)
Lead diameter 0.5 mm, 0.6 mm and 0.8 mm:
Load 5 N, 4 x 90°.
Lead diameter 1.0 mm:
Load 10 N, 4 x 90°.
Torsion (Uc) (for axial capacitors only)
Severity 1: Three rotations of 360°.
Severity 2: Two rotations of 180°.
Rapid change of temperature (Na)
The rapid change of temperature test is intended to
determine the effect on capacitors of a succession of
temperature changes and consists of 5 cycles of 30 min at
lower category temperature and 30 min at higher category
temperature.
Dry heat (Ba)
This test determines the ability of the capacitors to be used
or stored at high temperature. The standard test is 16 h at
upper category temperature.
Damp heat cyclic (Db)
This test determines the suitability of capacitors for use and
storage under conditions of high humidity when combined
with cyclic temperature changes and, in general, producing
condensation on the surface of the capacitor. One cycle
consists of 24 h exposure to 55 °C and 95 % to 100 %
relative humidity (RH).
Cold (Aa)
This test determines the ability of the capacitors to be used
or stored at low temperature. The standard test is 2 h at the
lower category temperature.
Damp heat steady state (Ca)
This test determines the suitability of capacitors for use and
storage under conditions of high humidity. The test is
primarily intended to permit observation of the effects of
high humidity at constant temperature over a specified
period.
The capacitors are exposed to a damp heat environment,
which is maintained at a temperature of 40 °C and an RH of
90 % to 95 % for the number of days specified by the third
set of digits of the climatic category code.
