TBJT04 - Injection Transformer

The TBJT04 injection transformer may be used for applications such MIL-STD-461 (CS101, CS106, CS109), DO 160 (section 16, section 18), ISO 11452 -10, SAE J1113-2 and various automotive manufacturer specific standards. Furthermore, it may be used to measure the input impedance of AC – and DC – power supplies using the Voltage / Current method. It provides galvanic isolation between the swept signal source on the primary side and the secondary side which is in series with the EUT supply line.
