Film capacitors are special capacitors, also known as polyester film capacitors, polypropylene film capacitors, polystyrene film capacitors, polycarbonate film capacitors, polyphenylene sulfide (PPS) film capacitors, polyvinyl fluoride (PVF) film capacitors, etc., and are classified according to their dielectric materials. Film capacitors use a dielectric material such as polyethylene terephthalate (PET) or polypropylene (PP). It has good insulation performance, can withstand high voltage, is lightweight, and a large capacitance can be obtained in a small volume, making it widely used. The R474F147050A1M is a film capacitor developed by a professional manufacturer.

The R474F147050A1M is a multi-layer structure film capacitor, and is specially developed for use in the automotive and LPG industry. It is mainly used for AC filter and resonance, anti-interference and energy storage in AC and high efficiency switching power supply. It is characterized by good performance, wide frequency range, low equivalent series resistance (ESR) and wide temperature range. It also has excellent solderability, long shelf life and reliable and stable performance.

The working principle of this film capacitor is to convert electrical energy into capacitive energy. The capacitor consists of two leads, usually referred to as terminals, which are separated by the dielectric material and the dielectric material acts as an insulator. Through the dielectric, electricity passes between the two leads and a potential difference is established. The potential difference causes a charge to appear on the positive terminal, while a negative charge appears on the negative terminal. An electric field is also established between the two terminals, and it is this field that holds onto the charge and stores electrical energy as a capacitive energy.

The capacitance of a film capacitor is mainly determined by its size and the dielectric material it uses. Among them, the main factors affecting the performance of the capacitor are the dielectric loss in the dielectric material and the thickness of the film. The thinner the film and the lower the dielectric loss in the dielectric material, the better the performance of the capacitor.

The R474F147050A1M film capacitor is a multi-layer structure capacitor developed specifically for automotive and LPG industry applications. Its wide frequency range, excellent solderability and reliable and stable performance have made it very popular in these markets. It is a cost-effective film capacitor and is suitable for use in AC filter and resonance, anti-interference and energy storage in AC and high efficiency switching power supply.
