Reliability testing of high voltage ceramic capacitors
1. series resistance test, insulation resistance test.
2ใtension test, i.e. the solidity of lead and chip welding.
3ใPositive and negative temperature change rate test, that is, the rate of change of capacitance under the condition of -40 degrees to +60 degrees.
Capacitor manufacturers
4ใAging test, the high-voltage ceramic capacitors of the ANC manufacturers operate under the simulated working environment for 30~60 days to test the decay and changes of its parameters.
5ใVoltage withstand test, including rated working voltage 24 hours working test; also including breakdown withstand voltage, i.e. destructive test, the one critical voltage before the capacitor is broken down is the breakdown voltage.
6ใLocal discharge test, i.e. partial discharge test.
7ใLife test, that is, on the basis of the aging test, the capacitor will be charged and discharged quickly under high-frequency impulse current, and the number of times of charging and discharging is the charging and discharging life, note that the life is derived after a long time of aging.
