The film capacitor has four dielectrics, and the dielectric materials are different. The performance of the thin film capacitor is also different. The development of PP() dielectric film capacitors miniaturized technology has become a widely used dielectric.

The film capacitor has four dielectrics, and the dielectric materials are different, and the performance of the thin film capacitor is different. Before the power electronics capacitor is widely used, small, low-cost PET is used as a general material, and the PET is suitable for a wide range of temperature ranges, and has higher adapters in home appliances, lighting and other fields. With the expansion of high frequency, large current applications, PP dielectric usage with excellent high frequency characteristics is improved, and the development of PP dielectric film capacitor miniaturization technology has made PP a widely used dielectric.

The PPS dielectric is closer to the PP dielectric, the PPS heat resistance is higher, and it is more suitable for high temperature environment, but the price is slightly higher, more for customized products.

PEN dielectric is high heat resistance, but compared to PP and PPS temperature characteristics, the application range is smaller.

PET: Polyethylene terephthalate is a common resin in life.

PEN: Ethylene glycol ester of polymethyl naphthalate is an emerging excellent polymer, and the chemical structure is similar to PET.

PP: Polypropylene, is a polymer formed by adding polymerization.

PPS: a new high-performance thermoplastic resin.
