What is Tantalum Capacitor?

Capacitor Types

1. What is Tantalum Capacitor?

Capacitors are components that can temporarily store electrical charge, and whose performance is determined by how much charge can be stored. As their name suggests, tantalum capacitors use tantalum to provide superior charge storage characteristics.

2. Capacitor Types

The 3 main types of capacitors on the market are aluminum electrolytic, multilayer ceramic, and tantalum capacitors. The characteristics and performance of each will differ due to the type of material used.
