The Capacitor Box allows for the introduction of an adjustable capacitance value into any electrical circuit. The box operates on a 'Make before Break' switching arrangement, ensuring that the circuit is never open while making a selection. It features two terminals for connecting wires or 4mm banana plugs, as well as a third terminal for earthing or shielding the housing. Each dial has 10 steps Accuracy: typically +/- 5% Capacitors for 11 Steps: 100pF, 220pF, 470pF, 1.0nF, 2.2nF, 4.7nF, 10nF, 22nF, 47nF, 0.1uF, 0.22µF. Product Code Item Max.
