Fracarro 289776 – 75 Ohm terminator CR75I

The Fracarro load resistor, code 289776, model CR75I, is a precision passive component designed for terminating lines in TV and satellite distribution systems. Unlike models with F connectors, the CR series is specifically designed to be inserted directly into the screw terminals of shunts, dividers, and feed-through sockets that do not have threaded connectors.

The CR75I model is an isolated resistor, which means it features an internal capacitor to block direct current (DC). This feature is essential in centralized or multi-switch systems where the cables carry power supply voltages for LNBs or amplifiers: the insulation prevents short circuits to ground, while still ensuring the perfect 75 Ohm impedance matching necessary to avoid signal reflections and standing waves.

Thanks to its compact design and optimized screw-type terminal, the CR75I ensures stable and long-lasting electrical contact. Use of this terminator is highly recommended on all unused feedthrough or branch outputs to maintain frequency response linearity across the entire bandwidth (5-2400 MHz) and prevent the ingress of electromagnetic interference.
