What's the difference between these two capacitors "JNC-JN222M" and "222-1KV"? I have these two ceramic capacitors shown in the image below: It seems to me that both of them have 2.2nF capacitance and the first one has 400V rated voltage while the other one has 1000V rated voltage.
The capacitor with the 250V AC rating is an X and Y rated capacitor and is capable of being applied across the incoming AC in your house. It's bigger because its reliability is much better i.e. it won't form a short circuit if it fails. Here's the idea behind them: -
@Andyaka I salvaged them from old electronic devices I don't have their datasheets. The capacitor with the 250V AC rating is an X and Y rated capacitor and is capable of being applied across the incoming AC in your house. It's bigger because its reliability is much better i.e. it won't form a short circuit if it fails.
Apply a DC voltage of 200% of the rated voltage (DC500V) or DC voltage of 150% of the rated voltage (DC1kV) for 1000 +48/-0 hrs. at 125±2°C with a relative humidity of 50% max. (Charge/Discharge current 50mA.) Pre-treatment : Capacitor should be stored at 125±3°C for 1 hr., then placed at *room condition for 24±2 hrs. before initial measurements.
However, in case the self-heating temperature is 20°C under a high-frequency voltage whose peak-to-peak value equals the capacitor's rated voltage, the capacitor's power consumption may exceed it's allowable electric power.
