Insulating Resistance

The value measured by applying DC 500V insulation   resistance tester between all terminals and snap ring with insulating sleeve   ≥100MΩ

Insulating Voltage

Apply AC 2,000V between all terminals and snap ring   with insulating sleeve for 1 minute and no abnormality appears.

Durability

Apply rated ripple current on capacitor with voltage   not more than rated voltage under 105°C environment and apply rated   voltage for 3,000 hours, then recover to 20°C environment   and the test results should satisfy the requirements as below
  Capacitance change rate (C)≤initial value±15%
  DF(tgδ)≤200% of initial specifications value
  Leakage current ≤initial specifications value

High-temperature Zero Load Feature

Capacitor is kept in 105°C environment for   1,000 hours, then test in 20°C environment and the test results   should satisfy the requirements as below
  Capacitance change rate (C)≤initial value±15%
  DF(tgδ)≤150% of initial specifications value
  Leakage current ≤initial specifications value
  (Voltage pretreatment should be done before test: apply rated voltage on both   ends of capacitor through a resistor about 1,000Ω for 1 Hrs, then discharge   electricity through 1Ω/V resistor after pretreatment. Place capacitor under   normal temperature for 24 Hrs after total discharging, then starts test.
