    Polyester Capacitor ESR

    What should a polyester capacitor 22nf 1000vh ESR should be ? I´m getting ~77 Ohms.

    ESR measurement is irrelevant for caps under 1uF as capacitive reactance at the measurement frequency comes into play too as the capacitance goes lower. Use a regular capacitance meter to measure those.
