surge voltage characteristics of ceramic capacitors
I am reading a datasheet from Murata for a ceramic capacitor. According to the datasheet: When AC voltage or pulse voltage is applied, the peak-to-peak voltage shall not exceed the rated DC voltage. I have googled a little and could not find any ceramic capacitor datasheet with surge characteristics.
How to choose capacitor voltage rating for ESD protection?
$color{red}{boxed{^1}}$ 195 volts is a little high due to the liberty I took when reducing the 50 MΩ resistor to 100 kΩ. I took this liberty to speed up the 150 pF charge time so that the sim result was more easily viewable. In reality, with basic charge redistribution from the 150 pF capacitor to the 10 nF capacitor, the peak voltage would …
The basics of capacitor banks protection
The capacitor can withstand 110% of rated voltage continuously. The capability curve then follows an inverse time characteristic where withstand is approximately 1 second -180%, 10 cycles -210%. Since the capacitors mostly are connected in series with a reactor it is not possible to detect overload by measuring the …

The capacitor can withstand a peak voltage of 550 V . If the voltage source operates at the resonance frequency, what maximum voltage amplitude can it have if the maximum capacitor voltage is not exceeded? *units need to be in V. There are 2 steps to solve this one. Solution. Step 1.
Technical Note
The thickness of the oxide layer determines the withstand voltage according to their direct proportional relationship. For the etching pits to be shaped to the intended thickness of the oxide layer, the pit patterns have been designed to have efficient surface area exten-sion depending on the intended withstand voltage (see Fig. 6)
