Hi Rick,
I am also figuring the ESR of capacitor!
The capacitor is (Kemet, ESK226M100AE3AA: 22 µF, 100 V)
Datasheet: KEM_A4004_ESK-1103206.pdf
According to the datasheet DF at (120 Hz 20°C (tanδ %)) is 10
I tried to calculate ESR=10%/(2pi x 120 x 22uF) =6.0286 (Ohms)
That value is looked like impossible and weird
Need help!!
Thank you
