Film capacitors, also known as plastic film capacitors, are types of capacitors that use a thin plastic film as dielectric. Through the use of different materials, the performance can be tailored to task-specific requirements. Since their invention, film capacitors have become an integral part of modern electrical and electronic circuits, providing essential functions such as signal filtering, energy storage, and coupling.

B32912B4223M000, a plastic film capacitor, is a part of number long of B32900 Series, produced by TDK Epcos Inc. This product has an advanced film technology with high temperature and high voltage capability. It specifically possess a smaller, more compact size, UL/CSA certification, and extended temperature ranges, making it suitable for a wide range of applications.

A film capacitor has two electrodes separating a film, usually made of polyester, polypropylene, dielectric ceramics, polycarbonate, and other polymers. The electrodes themselves are typically made of aluminum/zinc, nickel/cobalt alloys, or in rare cases, carbon powder. Once the capacitor is charged, an electric field will be produced across the dielectric. This electric field\'s magnitude is determined by the capacitance of the capacitor, which is based on the dielectric material, the thickness of the material, and plate areas between the capacitor electrodes that are touching the dielectric.

B32912B4223M000 has a metallic plate construction and is designed to have a long-term stability and low ESR/ESL properties. Its metallized polyester film dielectric provides an excellent insulation resistance. Its capacitor layers help reduce the dielectric loss and improves the linearity of capacitance. Moreover, this product is an self-healing capacitor, meaning that it is able to withstand high peak current and voltage surges without damaging the dielectric.

B32912B4223M000 has a wide range of applications. Its Metallized Polyester Film Dielectric makes it a popular choice in power supply line bypass filter, mains filters, other switch mode power supplies, and other EMI/RFI filters. Its self-healing properties make it ideal for motor / lighting starters, DC/DC converters, rectifiers in video displays, controllers, UPS inverters, battery chargers, propulsion systems, and power electronics.

The B32912B4223M000 is a reliable and effective solution for many power-related applications. Its metallized polyester film dielectric provides excellent insulation attributes, its self-healing properties can withstand high peak current and voltage surges, and its long-term stability and low ESR/ESL properties ensure reliable performance.
