Film capacitors, also known as plastic film capacitors, are composed of a dielectric film and two metal plates (electrodes). This film serves as a dielectric medium and isolates the two metallic plates from each other. Film capacitors are quite reliable and are ideal for use in a variety of areas; they are mainly used in applications such as frequency modulation oscillators, antenna matching networks, power factor correction, voltage surge protection, and resonance suppression. The SFA66T2K219B-F is an ideal choice when specific electrical properties are required.

Construction and Working Principle of SFA66T2K219B-F

The SFA66T2K219B-F is a metallized polypropylene film capacitor, where each of the two metal electrodes are made of metal film and then attached to the dielectric film, or substrate. The metal film provides enhanced stability and reliability. The electrodes (also known as a winding) are connected to two metallic terminal plates. The SFA66T2K219B-F is a Class X2 film capacitor, which means it meets IEC 60384-1 and EN 132400 standards.

The working principle of SFA66T2K219B-F is the same as that of any capacitor. When you pass a current through it, electric charge is stored and a potential difference is created between the two electrodes. As the electric field increases, the electric charge builds up and accumulates on the electrodes. This stored charge is what makes it possible for SFA66T2K219B-F to serve its intended function.
