Film capacitors, also known as plastic capacitors, are polarized capacitors that are constructed with an aluminium foil plate or other parallel plate structure and a dielectric plastic film such as polystyrene, polyester, polycarbonate or polypropylene. The plates are then rolled up and molded in a case for protection. The 254LC3700K5LM8 is one such type of film capacitor.

Application Field

The 254LC3700K5LM8 is a special type of film capacitor, designed for use in a wide range of applications such as lighting, power, and industrial applications. It is most commonly used as a fast-acting, low-ESR capacitor in switching power supplies, as well as for power factor correction and for DC-DC conversion.

Working Principle

A film capacitor is a device made up of two metal plates separated by a dielectric material. When a voltage is applied across the plates, an electric field is generated which creates an electric charge on the plates. This electric charge produces an opposing electric field which prevents further charge accumulation, thus creating a capacitive effect. Since the dielectric material has a dielectric constant that is greater than that of air, the capacitance is much greater than that of an air-filled capacitor.

The dielectric used for the 254LC3700K5LM8 is polypropylene which offers the benefits of low losses, stability over temperature and time, and good electrical insulation properties. These properties make it ideal for applications such as switching power supplies, power factor correction, and DC-DC converters.

In addition, the capacitor has a low ESR (equivalent series resistance), which means that it can absorb and dissipate energy more efficiently, making it an ideal choice for fast-acting, low-ESR applications. It also has a low insert loss, which means that it has very little energy loss due to its low ESR. This feature makes it suitable for applications involving high current pulses.

The 254LC3700K5LM8 is also a long life product, providing up to 5000 hours of operation. The self-healing properties of the dielectric and confined capacitor design offer excellent protection against short circuits and over-voltage conditions. This makes it an ideal choice for applications where reliability is of paramount importance.
