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 trimmer capacitor: characterized by abrasion resistance and long service life.

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

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

4) Cylindrical trimmer capacitor: complex structure and high accuracy.

5) Film dielectric trimmer capacitor: the same structure as mica trimming capacitor, but with smaller dielectric size. There are double couplet products.

6) Short wave dedicated trimmer capacitor: dedicated shortwave band for radio, with a small range of variation, only 2.2pF, but has a longer life span of more than 10000 times.
