VARIABLE CAPACITORS AND TRIMMER

Variable capacitors and trimmer are capacitor capacitance value can be changed. This capacitor can be changed because of physical capacity has a shaft that can be played using a screwdriver with a minimum-maximum range.

VARIABLE CAPACITORS AND TRIMMER

 

Variable capacitors and trimmer is typically used in radio tuner to vote a certain frequency waves captured, in addition to the variable capacitor and the trimmer is also used in other electronic devices that require capacitance values ​​are not fixed.

Here is a brief description that will distinguish between the variable capacitor and trimmer:

Variable capacitor

Variable capacitor is made of metal, has a maximum capacity of about 100 pF (pikofarad) up to 500 pF (100 pF = 0.0001 μF).

The capacitor value can be seen in the writings contained in the body. For example, 10 μF / 16 V means that the capacitor value is 10 microfarads and can work at a maximum voltage of 16 V. If it exceeds 16 V then this capacitor will have to "break down".

Trimmer 

Actually there is no much difference with the variable capacitor trimmer only the capacity of the variable capacitor is smaller than that under 100 pikoFarad. For the selection of the frequency band, in a series trimmer capacitor in parallel with a variable.
