Free QuoteTuning capacitors take a host of forms. Some are adjusted by means of screwdrivers or tuning tools. These are generally called trimmers or padders. They are set for resonance just once, then left in that posi- tion. Trimmer capacitors may be made with metal plates; insulation between the plates can be made of ceramic, plastic, mica or glass.
Because of this ability to change the resonant frequency, the variable capacitor is called a "tuning capacitor" or a "resonating capacitor." The electrical equivalent of the parts in Fig. 1 is offered in Fig. 2. The arrow through the capacitor indicates it is ad- justable.
In circuits where high RF power is developed, it is wise not to allow dc voltage to be applied to the tuning capacitor, even though some amateurs have done this in homemade gear. Fig. 7 shows both methods, but the illustration at B is recom- mended for safety reasons as well as voltage- breakdown considerations.

Some trimmer capacitors resemble the larger variable capacitors, except that they are Fig. 3 — A collection Of trimmer and padder capacitors. These units have variable capacitance, but are not suitable for use as a main-tuning control because they have no shafts on which to mount a knob or dial mechanism.
