Film Capacitors

Film capacitors, also known as plastic film capacitors, are a type of capacitor, a passive electrical component, generally smaller in size than most conventional capacitors. They offer a higher degree of reliability, radiant stability and temperature stability compared to other types, such as ceramic or aluminum electrolytic capacitors. Film capacitors come in a variety of styles, including plastic (or other types of non-solid dielectric) film capacitors and metalized film capacitors. Plastic film capacitors are usually created using an insulating ceramic core, which is then insulated with a thin film of plastic, such as polystyrene.

ECQ-E6155KF Application Field and Working Principle

The Panasonic ECQ-E6155KF is a film-type capacitor specifically designed for automotive use in applications such as engine start circuits, fuel pumps, exhaust fans, and DC link circuits. Using a high-temperature-resistant epoxy resin for the dielectric layer, it is suitable for operation in the high-temperature conditions of the engine compartment. It also uses a polyester-coated film for the winding material to provide excellent high-temperature and high-humidity properties.

The ECQ-E6155KF features a very low effective series resistance (ESR), which results in a high ripple current allowance, even at low frequencies (up to 100 kHz). This makes it an ideal choice for high-frequency switching systems and voltage regulator applications. The capacitor also features an integrated metallic film terminal, allowing it to be directly mounted on printed circuit boards. Finally, the ECQ-E6155KF is subjected to a rigorous quality control system for automotive equipment and is supplied with an UN Product certification, guaranteeing its quality and reliability.

The working principle of the ECQ-E6155KF is straightforward. The capacitor stores electrical energy between two conductive plates which are separated by an insulating material (dielectric). When voltage is applied to the capacitor, current flows through the dielectric and generates an electrostatic field between the two plates. This electrostatic field can then store energy. When the voltage is removed, the stored energy is released as a current.

In summary, the Panasonic ECQ-E6155KF is a film type capacitor specifically designed for automotive applications such as engine start circuits, fuel pumps, exhaust fans, and DC link circuits. It offers excellent high-temperature and high-humidity properties, low ESR, high ripple current allowance, and integrated metallic film terminals for direct mounting on printed circuit boards. It is subjected to rigorous quality control and is supplied with an UN Product certification.
