Film Capacitors

A film capacitor, otherwise known as a plastic film capacitor, a polyester capacitor, or a Mylar capacitor, is a capacitor that is made using thin film of plastic film as the dielectric. It exists in a wide variety of capacitor types: single layer, dual layer, and stacked layer configurations. BFC2373EF155MF is one of the most commonly used film capacitors.

BFC2373EF155MF application field and working principle

Film capacitors are widely used in many industries, from automotive and transportation to consumer electronics, defense, lighting, medical, and telecommunications. BFC2373EF155MF capacitors are most commonly used in power filtering, decoupling, and transient suppression applications, usually in the voltage range of 5 KV and below. BFC2373EF155MF capacitors are typically configured as polyester film with metal foil electrodes and typically used on AC ripple current filters.

The working of a film capacitor mainly depends upon the dielectric material that is used between the conductive plates. The most common dielectric materials used for film capacitors are polyethylene, polypropylene, and polyester, all of which are polymer films. Each material has different electrical, chemical, and mechanical characteristics that must be taken into consideration when choosing a film capacitor. BFC2373EF155MF capacitors are specifically designed with polyester film due to its superior electrical insulation and mechanical integrity.

The electrical characteristics of BFC2373EF155MF capacitors make them ideal for certain applications. They offer high capacitance, low voltage breakdown, low leakage current, and high frequency performance. BFC2373EF155MF capacitors also provide excellent EMI and RFI suppression capabilities. Additionally, they offer a dielectric constant that is independent of operating temperature and frequency.

The capacitance that is achieved from a BFC2373EF155MF capacitor depends upon the area of the metal surfaces exposed to the interlayer and the thickness of the dielectric. This means that by using more layers, the capacitance can be further increased. BFC2373EF155MF capacitors also have a high voltage rating, allowing them to be used in high voltage applications.

In general, BFC2373EF155MF capacitors are more reliable than other types of capacitors because of their superior insulation properties. This allows them to safely operate even at high currents and temperatures. Furthermore, their long service life minimizes the need for maintenance and replacement, making them cost-effective for industrial use.

Overall, BFC2373EF155MF capacitors are an excellent choice for a variety of applications where high capacitance, high voltage rating, low leakage current, EMI/RFI suppression, long service life, and low cost are needed.
