Capacitors

A capacitor is a passive two-terminal electrical component that stores potential energy in an electric field. The effect of a capacitor is known as capacitance. While some capacitance exists between any two electrical conductors in proximity in a circuit, a capacitor is a component designed to add capacitance to a circuit.

More capacitance requires a larger capacitor. Plates with more overlapping surface area provide more capacitance, while more distance between the plates means less capacitance.

The material of the dielectric even has an effect . In a way, a capacitor is a little like a battery. Although they work in completely different ways, capacitors and batteries both store electrical energy. If you have read How Batteries Work, then you know that a battery has two terminals. Inside the battery, chemical reactions produce electrons on one terminal and absorb . A basic overview of capacitors and capacitance.

Introduction to the capacitance of a two plate capacitor. A simple explanation of how capacitors store electricity and the different jobs they do in electronic circuits.

The capacitor is made of close conductors (usually plates) that are separated by a dielectric material. The plates accumulate electric charge when connected to power source. One plate accumulates positive charge and the other plate accumulates negative . This definition explains what a capacitor is and how it works.

Murata offers many types of capacitors as Ceramic, Polymer Aluminum Electrolytic, Trimmer, Supercapacitor (EDLC), Single Layer Microchip, Variable. We have fixed and variable capacitors , networks and arrays and more in-stock and ready to ship today.

Working voltage: Since capacitors are nothing more than two conductors separated by an insulator (the dielectric), you must pay attention to the maximum voltage allowed across it.

If a circuit is driven by a battery, the battery will charge capacitors until the voltage across the capacitor perfectly opposes the voltage from the battery, resulting in an effective open circuit in . Capacitors are in stock at DigiKey. For Higher physics, learn the key features of characteristic graphs for capacitors. Use graphs to determine charge, voltage and energy for capacitors. NIC Components has a wide variety of capacitors , including tantalum electrolytic, ceramic, double layer, aluminum electrolytic, and thick and thin film.
