Analyze the development status of metallized film capacitors

The development of metallized film capacitors in China: Since the advent of hand-produced metallized film capacitors in the 1960s, China's metallized film capacitors have experienced three development tides, and in the 1980s, the introduction of technical transformation from manual operation to stand-alone automation was completed by the opportunity of color TV production.

In the 1990s, the "short, small, light and thin" of the electronic machine completed the technical transformation of the miniaturization (winding type and metalized stacking type) of metallized film capacitors, and since the beginning of this century, in order to meet the reliability requirements of the electronic machine, it has undergone a technical transformation based on safety regulation capacitors. In recent years, metallized film capacitors have ushered in a fourth wave of joint-stock and private investment-based development.

The advantages of metallized film capacitors: metallized polyester film winding, non-sensational structure epoxy resin envelope, CP line one-way lead-out better performance, high insulation resistance, stable electrical capacity. Suitable for DC and pulsation circuits, widely used in a variety of electrical and electronic electrical equipment filtering, insulation, bypass, coupling and noise reduction and other occasions

Metallized film capacitors can achieve 10 to dozens of times the rated ripple current of aluminum electrolytic capacitors of the same capacity, aluminum electrolytic capacitors in order to achieve higher current resistance, usually using a larger capacity to meet the requirements, and larger capacity is an unnecessary waste of cost and installation space. Therefore, metallized film capacitors are in demand in the market.
