Working Principle

Tantalum capacitors work on the principle of an electric field inducing charge onto the plate or dielectric. The electric field produces a surface potential that attracts ions of both polarities and generates an electric field. This electric field creates a surface potential that brings in more electrons and keeps the capacitor charged. The electric field also helps to control the equivalent series resistance of the capacitor. The M39003/03-4012H series capacitors are designed to operate at high temperatures and are suitable for high-performance applications.
