Vibration resistance

test

To IEC 60068-2-6, test Fc:

Displacement amplitude 0.35 mm, frequency range 10 Hz ... 55 Hz,

acceleration max. 5 g, duration 3

× 2 h. Capacitor mounted by its body

which is rigidly clamped to the work surface.

Characteristics at low

Max. impedance ratio

at 100 Hz

≤ 250 V

≥ 400 V

Z -25 °C / Z 20 °C 4

Z -40 °C / Z 20 °C 7

IEC climatic category

To IEC 60068-1:

≤ 250 V DC: 40/105/56 ( 40 °C/+105 °C/56 days damp heat test)

≥ 400 V DC: 25/105/56 ( 25 °C/+105 °C/56 days damp heat test)

The capacitors can be operated in the temperature range of

°C to +105 °C but the impedance at 40 °C should be taken

into consideration.
