Ceramic Trimmer capacitor is a semi-fixed adjustable capacitor, and its electrostatic capacity can be changed freely.

The working principle of JKA trimmer capacitor: Change the overlapping area of electrodes. One of the electrodes is fixed to sandwich the dielectric, and the other is made as a variable electrode. The change in the overlapping area of the two electrodes (the area of the opposite electrode) can change the electrostatic capacitance.

jb Capacitors Company’JKA series: surface mount ceramic trimmer capacitors with mini size, five kinds of capacitance values, different color is easily identified.
