I 'm a bit confused with the math of ripple curent after reading the 2 different datasheets . Capacitor A is 640mA at 100kHz and Capacitor B is 146mA at 120Hz.
So What is the ripple current for Capacitor B at 100kHz? Which one has a higher ripple current?
Also, some of the miniature capacitor datasheets don't list the Impedance or ESR , and only Impedance ratio is listed. Is there any way to find out the impedance?
*******************************************************Capacitor A: Rated ripple current(mA/rms 105c,100kHz): 640
Capacitor B: Rated ripple current(mA/rms at 120 Hz,105=B0C): 146 Frequency Multipliers: 1.20 For 10K Freq.(Hz)
