TBJT01 wideband injection transformer

The TBJT01 is a wideband injection transformer for control loop stability measurements. It provides galvanic isolation between the swept signal source and the control loop. The injection transformer is internally terminated with a 5 Ohm resistor and protected with a 100 mA fuse. The usable frequency range is 10 Hz to 45 MHz.
