Code: IPC-5865-X

Class set of 15 Capacitance Substitution Boxes. The IPC Capacitance Substitution Box (IPC-5861-X) provides the easily selection of 12 preferred value capacitors, ranging from 100pF to 0.47µF. The values range from: 100pF, 220pF, 470pF, 1nF, 2n2, 4n7, 10nF, 22nF, 47nF, 0.1µF, 0.22µF and 0.47µF. All the capacitors offer a maximum voltage rating of 50V (AC or DC), with actual capacitance value tolerances of ±5% to ±10%. The unit is housed in a robust ABS plastic case with rotary selector switch and a pair of 4mm connection sockets.
