Variable CapacitorsVariable Capacitors

Variable capacitors have capacitance values that can be varied by applying voltage to their electrodes.

Variable Capacitors

Regarding Continuous and Polling

Continuous means that the specified voltage is continuously applied for Port1,2.

Polling means that the specified voltage is switched on and off and applied for port1,2.(on: 40msec, off: 360msec)

Selection guide

Please choose the suitable VAC for the required tuning range and step.

Max. tuning voltage: 3.0 V
