What are the different types of capacitors?

Visual Guide to Capacitor Types. Browse capacitor by how they look. Electrolytic Capacitors, Aluminum Capacitors, Film Capacitors, Ceramic Capacitors, Tantalum Capacitors, Silver Mica Capacitors, Glass Capacitors, Oil Capacitors, Surface Mount Capacitors, Variable and Fixed Capacitors.

What are the specifications of a capacitor?

Capacitors have several key specifications that define their performance and suitability for various applications. Some of the most important capacitor specifications are mentioned below : Capacitance is the fundamental property of a capacitor and is measured in Farads (F).

How do I choose a replacement capacitor?

There is also a general recommendation, when you are unable to find an exact replacement part, to choose an alternative with a higher capacitance. When choosing a replacement capacitor trying to get as close to the original value as possible is ideal but depending on the use there is some flexibility.

What is a good tolerance for a capacitor?

Common tolerances include ±5%, ±10%, and ±20%. Tighter tolerances indicate greater accuracy. The dielectric material between the capacitor plates determines its performance characteristics. Different dielectric materials offer varying levels of capacitance, voltage rating, temperature stability, and other properties.

What is a capacitance of a capacitor?

Capacitance is the fundamental property of a capacitor and is measured in Farads (F). It determines the amount of electrical charge a capacitor can store per unit voltage. Higher capacitance values indicate a greater ability to store charge. Fig 1 : Electrolytic capacitor with capacitance value, voltage rating and terminal marking.

Why are capacitors used in high voltage power correction & smoothing circuits?

Some kind of capacitors (like electrolytic capacitors) can charge up to higher voltages. So they are used in high voltage power correction and smoothing circuits. The differences between the different types of capacitors are generally made with according to the dielectric material which is used between the metal plates.
