Simple classification of metal film capacitors and other capacitors

With more and more applications of metal film capacitors, our frequency of use has gradually increased. The classification of metal film capacitors and other capacitors is also a very simple introduction for this editor. Let's go down with the editor!

There are many types of capacitors, which can be generalized into two categories:

Category one: According to the different types of insulation materials (dielectrics) used.

1. Solid inorganic dielectric capacitors. Such as ceramic capacitors, mica capacitors, monolithic capacitors.

2. Solid organic dielectric capacitors, such as polyester film capacitors, polypropylene capacitors, polyester capacitors, and other metal film capacitors.

3, electrolytic capacitors, such as aluminum electrolytic capacitors (CD) and other electrolytic capacitors.

Category two: According to the structure of the capacitor classification.

1. Fixed capacitor: A capacitor whose capacity cannot be changed.

2. Variable capacitors and trimmer capacitors: Capacitors whose capacitance can be manually adjusted within a certain range and a small range. It can also be divided into filter capacitors, coupling capacitors, and bypass capacitors, depending on the application. In short, in general electronic circuits, there are basically three types of capacitors: a fixed capacitor, a trimmer capacitor, and an electrolytic capacitor.

The metal film capacitor directly evaporates a thin layer of metal on the plastic film as an electrode. This evaporated metal layer is thinner than the usual metal foil, which is a metallized film capacitor. Metal film capacitors are generally used in low-frequency circuits, and CBB capacitors in metal film capacitors are used in many circuits and have better performance.
