Example

C = 330 nF - 100 V used for the voltage signal shown in next drawing.

UP-P = 80 V; UP = 70 V; T1 = 0.5 ms; T2 = 1 ms

The ambient temperature is 35 °C

Checking conditions:

1. The peak voltage UP = 70 V is lower than 100 VDC

2. The peak-to-peak voltage 80 V is lower than 22 x 63 VAC = 178 UP-P

3. The voltage pulse slope (dU/dt) = 80 V/500 μs = 0.16 V/μs

This is lower than 20 V/μs (see specific reference data for each version)

4. The dissipated power is 60 mW as calculated with fourier terms

The temperature rise for Wmax. = 8.5 mm and pitch = 15 mm will be 60 mW/11 mW/°C = 5.5 °C

This is lower than 15 °C temperature rise at 35 °C, according figure “Max. allowed component temperature rise”
