Replacing Capacitors With Different Values Guide

Capacitance, or capacitance rating, is the amount of energy that can be stored in the capacitor. The higher the capacitance rating, the more energy that can be stored. Generally speaking, you should always replace like-for-like when it comes to capacitors – meaning if your capacitor has a capacitance rating of 10μF, you should …
