Introduction

Aluminum Electrolytic Capacitors are used for many applications, ranging from power supplies, to handling high pulse current, to audio applications, and more. ESMR421VSN221MP35S is a aluminum electrolytic capacitor designed for high temperature, performance and energy storage applications, suitable for electric vehicles, telecommunications, and power supplies. It comes with a lead finger terminal for easy installation, and a RoHS-compliant coating and body. It is low leak capacitance, low impedance, and has long shelf life.

Working Principle

An electric double layer capacitor works on the principle of two charged layers on the surface of a solid. This consists of two electrodes, an anode and a cathode. The anode is the positively charged layer, while the cathode is the negatively charged layer. In between, a solid dielectric insulator exists.

When a voltage is applied across the two electrodes, a chemical reaction occurs. The anode is oxidized, releasing electrons, and the cathode is reduced, gaining electrons. This creates an electrostatic field between them, which acts as the dielectric, or electrical insulator. This electrostatic field is what stores the electric charge within the capacitor.

The ESMR421VSN221MP35S capacitor is a high-performance aluminum electrolytic capacitor specifically designed to provide high energy storage. It has been designed with a specially-processed electrolyte and a uniquely designed lead finger for improved heat dissipation. The improved heat dissipation ensures the stability of the capacitor, allowing it to withstand higher temperatures and higher current pulses. This makes the ESMR421VSN221MP35S a highly-reliant and long-lasting capacitor.
