Designing PCBs with Electrolytic Capacitors – Fencon

The negative lead of the capacitor should be connected to the negative side of the circuit, and the positive lead to the positive side. Connecting an electrolytic capacitor in reverse can cause it to fail or even explode, which can damage the PCB and other components.

Is there any reason why I can''t extend the legs of this capacitor to move it to a more convenient position? More info in comments. : r ...

Since it looks like this capacitor is part of a switching DC/DC regulator, you should also expect some ripple current in those leads - so longer wires might emit more EMI. That being said, it already has long leads and is a slow acting electrolytic style capacitor, so 2cm of wires shouldn''t make it any worse.

Lab Notes on Capacitors

A capacitor is an electrical device for storing charge. In general, capacitors are made from two or more plates of conducting material separated by a layer or layers of insulators. The capacitor can store energy to be returned to a circuit as needed. The capacitance (C) is defined as the ratio of the stored charge (Q) to the potential difference (V) between the …
