Film capacitors, also known as film dielectric capacitors, are components used in various electrical circuits in various electrical components, systems, and equipment, such as TVs, radios, aircraft systems, lighting systems, automobiles, testing systems, and various electronic and electrical machinery. Film capacitors refer to a class of capacitors whose dielectric layers are mostly plastic films, such as polypropylene film, polyester film, polycarbonate film, and other film materials.

SFC37T30K291B-F is a kind of film capacitor with high quality. It is a solid film capacitor with a cylindrical body and a radial lead. The cylindrical body is generally made of polypropylene film as a dielectric material, and the electrode is connected by tin plated ears. The SFC37T30K291B-F is suitable for a wide range of applications, such as DC-Link, AC filtering, and pulse applications.

The working principle of SFC37T30K291B-F is based on the standard electric field capacitors, which are characterized by their electrostatic storage of electric charge. When a capacitor is connected to a circuit, it stores electric energy in the form of electric charge on its conducting plates. The electric charge accumulates on each plate, depending on the voltage applied, until the potential difference between the plates equals the applied voltage. The stored electrical energy in the capacitor is converted into a current as the voltage changes. Because of this, capacitors have the ability to act as a filter or suppressor of slowly changing voltages.

The operating voltage of SFC37T30K291B-F capacitors is 300VDC, and its nominal capacitance is 30,000pF. It can operate in temperatures ranging from -40C to +85C, and its capacitance stability is ±1.6%. This capacitance also maintains a high level of safety due to its radially symmetrical design, which helps reduce internal stress and keeps the capacitance from breaking down.
