1. 2. Non-polar Capacitors Polar capacitors or polarized capacitors are such type of a capacitor whose terminals (electrodes) have polarity; positive and negative. The positive terminal should be connected to positive of supply and negative to negative. Reversing the polarity will destroy the capacitor.
Polarized capacitors have distinct positive and negative terminals. The positive terminal, or anode, must be at a higher voltage than the negative terminal, or cathode, for the capacitor to function correctly. A common type of polarized capacitor is the Electrolytic Capacitor.
Polar capacitors or polarized capacitors are such type of a capacitor whose terminals (electrodes) have polarity; positive and negative. The positive terminal should be connected to positive of supply and negative to negative. Reversing the polarity will destroy the capacitor. These type of capacitors are only used in DC applications.
The anode is a metal forming an anodized layer within a dielectric material. 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.
Reversing the polarity can lead to damage or even explosion. The positive terminal is usually marked with a “+” symbol or a longer lead. Tantalum Capacitors: Similar to electrolytic capacitors, tantalum capacitors are polarized and have a positive and negative terminal.
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. An arrow band with a ‘-‘ sign represents the negative polarity on a capacitor.
