Capacitor anode cathode identification (Easy ways 2024)
Capacitor anode cathode identification is very important when you are working with electrolytic capacitors. Wrong pin connections can lead to bad results and sometimes can damage your capacitor. There are two easy methods through which we can tell which leg of the capacitor is a positive anode or negative cathode.
Component Orientation and Polarity
Capacitors typically have straightforward polarity markings: a plus (+) sign for the positive terminal and a minus (-) sign for the negative terminal. In the below image, shorter lead and line arrows indicate negative terminal.
How to Identify Capacitors
How to Identify Electrolytic Capacitor. Electrolytic capacitors offer high capacitance values and are commonly used in power supply and filtering applications. To identify electrolytic capacitors: Check Physical Appearance: Electrolytic capacitors have cylindrical or rectangular shapes with polarized terminals.

What is an Electrolytic Capacitor
Except for cylindrical led (single-ended) and SMD polymer capacitors, electrolytic capacitors with solid electrolytes have a polarity marking on the anode (plus) side. ... An electrolytic capacitor has two leads of uneven length within which the shorter one is negative and the longer one is positive. Film capacitors are non-polar so they have ...
Capacitors
They have a positive pin -- the anode -- and a negative pin called the cathode. When voltage is applied to an electrolytic cap, the anode must be at a higher voltage than the cathode. The cathode of an electrolytic capacitor is usually identified with a ''-'' marking, and a colored strip on the case.
