Trimmer Capacitor

The trimmer capacitor is also called semi adjustable capacitor, and its capacity is between 5 and 45pF. There are many kinds of them, and the following are the following:

1) Ceramic trimming capacitors: characterized by abrasion resistance and long service life.

2)Tube type trimming capacitor: also known as the wire trimming capacitor, for single use. It is often used on radio.

3) Mica trimming capacitor: small in size, often used in radio.

4) Barrel type trimming capacitor: complex structure and high accuracy.

5) Film dielectric trimming capacitors: same as mica trimming capacitors, but with smaller dielectric materials. There are double couplet products.

6) Short wave special trimming capacitor: dedicated to the short wave band of radio, with a small change range, only 2.2pF, but long life, more than 10000 times.
