How to choose capacitor voltage rating for ESD protection?
The capacitors will need to have a voltage rating that is higher than the highest DC voltage that will ever be across that capacitor during normal operation. The idea of proper ESD protection using capacitors is that the voltage will never become very high in the first place. The capacitors are supposed to absorb the charge from injected …
How to Test a Capacitor?
Why do we need to Test a Capacitor? When a capacitor is placed in an active circuit (a circuit with active current flowing), charge starts to build up in the capacitor (on one of its plate) and once the plate of the capacitor can no longer accept any more charge, this means the capacitor is fully charged. ...
