Talking about small high-voltage film capacitors

There are many types of film capacitors, mainly polyethylene capacitors, polypropylene capacitors, polystyrene capacitors, and polycarbonate capacitors. So what is a small high-voltage film capacitor?

A small-sized film capacitor relates to a capacitor structure including two leads, a capacitor core, and a body. The capacitor core in the body uses a metallized film layer as a dielectric and an aluminum foil as an electrode. The end face is connected to the aluminum foil by a gold-sprayed layer. Leads and end faces are soldered and led out. The main body is wound with a dielectric and an electrode, and is powdered with epoxy resin. Seal combination.

It is characterized in that the nominal pitch of the leads is no more than 5mm, and the capacitor core is wound by a metallized film of a series structure, which is composed of a thin film and a metal plating layer attached to the thin film. And the metal has an edge structure on one or both sides or in the middle of the film.

The small structure film capacitor solves the problem of low reliability, short life, and cannot meet the requirements of ultra-small size of low-power energy-saving lamps. High rated operating voltage, less waste, save resources and help improve the environment. And it is resistant to temperature shock and can work normally for a long time in the working environment of 85 ℃ -110 ℃.

Excellent charge and discharge resistance, especially suitable for start-up and free-wheeling capacitors that require energy-saving lamps. It is also suitable for LC, RC oscillator circuits, differential circuits, switching acceleration circuits and transistor overvoltage protection circuits. This capacitor has a long life, high reliability, and environmental protection, and can be used in applications that require high voltage, high current, and small size.
