Trimmers, Variable Capacitors are in stock at Tenco Electronics.A variable capacitor is a capacitor whose capacitance may be intentionally and repeatedly changed mechanically or electronically. Variable capacitors are often used in L/C circuits to set the resonance frequency, e.g. to tune a radio (therefore it is sometimes called a tuning capacitor or tuning condenser), or as a variable reactance, e.g. for impedance matching in antenna tuners.Tenco offers inventory, pricing, & datasheets for Trimmers, Variable Capacitors.
