Capacitor Specifications: what they mean
Selecting Capacitor Current Rating – Know the Ripple Current If you are not an electronics hobbyist or working on the field for some time, you may not familiar with the term ripple current. This is the term given to the current that will pass through the capacitor.
How can I determine the current rating of a capacitor?
Most capacitors don''t actually have a "current" rating, since that doesn''t make much sense. You can''t put a sustained current through a capacitor anyway. If you tried, its voltage would rise linearly, and then you''d get to the voltage limit where you''d have to stop.
