Capacitor classification

1. According to the structure, there are three categories: fixed capacitors, variable capacitors, and trimmer capacitors.

2. Classified by electrolyte: organic dielectric capacitors, inorganic dielectric capacitors, electrolytic capacitors, and air dielectric capacitors.

3, according to the use of: high frequency bypass, low frequency bypass, filtering, tuning, high frequency coupling, low frequency coupling, small capacitors.

4. According to different manufacturing materials, it can be divided into: ceramic dielectric capacitor, polyester capacitor, electrolytic capacitor, tantalum capacitor, and advanced polypropylene capacitor.

5. High-frequency bypass: ceramic capacitors, mica capacitors, glass film capacitors, polyester capacitors, glass glaze capacitors.

6. Low frequency bypass: paper capacitors, ceramic capacitors, aluminum electrolytic capacitors, polyester capacitors.

7. Filtering: aluminum electrolytic capacitors, paper capacitors, composite paper capacitors, liquid tantalum capacitors.

8. Tuning: ceramic capacitors, mica capacitors, glass film capacitors, polystyrene capacitors.

9. Low coupling: paper capacitors, ceramic capacitors, aluminum electrolytic capacitors, polyester capacitors, solid tantalum capacitors.

10. Small capacitors: metalized paper capacitors, ceramic capacitors, aluminum electrolytic capacitors, polystyrene capacitors, solid tantalum capacitors, glass glaze capacitors, metalized polyester capacitors, polypropylene capacitors, mica capacitors.

Siren Speaker

Siren speaker:

Siren speaker is a kind of micro speaker unit which uses a diaphragm made of Mylar material. Mylar speakers are of ultrathin design and lightweight and clear voice. It is widely used in security industry (e.g. siren, alarm, smoke detector..).

There are two types of Mylar speakers from the shapes:

1) Round shapes, we have products from 10mm to 57mm in diameter.

2) Oblong shape, we have products in sizes of 1510/1712/1813-..
