Capacitance can be adjusted within a small range, and can be fixed to a certain capacitance value after adjustment.
Ceramic trimmer capacitor Q value is high, the volume is small, usually can be divided into two kinds of round tube and wafer.
Mica and polystyrene media are usually spring-type East, the structure is simple, but the stability is poor.
Wirewound porcelain trimmer capacitor is removed copper <external electrode> to change the capacitance, so the capacity can only be smaller, not suitable for repeated use of the occasion to debug
