In-circuit Test Probe Pogo Pin P078 Series for Printed Circuit Board Assembly In-circuit test probes are mainly used for testing electrical performance of in-circuit components on PCB and the connection between circuit networks. It could quantitatively measure components such as resistors, capacitors, inductors, crystal oscillators, and perform functional tests of diodes, triodes, optocouplers, transformers, relays, operational amplifiers, power supply modules and integrated circuits. We will introduce in-circuit test probe P078-BK-346 series here. The diameter is 0.78 mm and the total length is 34.6 mm. Various tip styles, for example, BK, H, S, T, E, C, U, G, etc., are available for test probes. For details, please check below parameters.
