Example
C = 330 nF - 63 V used for the voltage signal shown in next drawing.
UP-P = 40 V; UP = 35 V; T1 = 100 μs; T2 = 200 μs
The ambient temperature is 35 °C
Checking conditions:
1. The peak voltage UP = 35 V is lower than 63 VDC
2. The peak-to-peak voltage 40 V is lower than 22 x 40 VAC = 113 UP-P
3. The voltage pulse slope (dU/dt) = 40 V/100 μs = 0.4 V/μs
This is lower than 60 V/μs (see specific reference data for each version)
4. The dissipated power is 16.2 mW as calculated with fourier terms
The temperature rise for wmax. = 3.5 mm and pitch = 5 mm will be 16.2 mW/5.0 mW/°C = 3.24 °C
This is lower than 15 °C temperature rise at 35 °C, according figure “Max. allowed component temperature rise”
