R404012120 Description

Short technical summary and product information.

The Radiall R404012120 is a BNC male coaxial termination designed for 75 Ohm systems. It operates from DC to 1 GHz with a VSWR of ≤1.08 from DC to 0.5 GHz and ≤1.15 from 0.5 to 1 GHz. The termination has a DC resistance of 75 Ohm ± 2% and can handle an average power of 1 W in free air cooled conditions at 25°C. Peak power rating is 500 W for 1 µs pulse at 1% duty cycle.

 

Construction features a brass body with nickel plating, a gold-plated brass center contact, and a PTFE dielectric. The resistor is thick film on an alumina substrate. The termination is free-hanging and cap-style, weighing 15.87 g. It complies with MIL C39012 standard.

 

Operating temperature range is -55 to +125 °C, with storage in the same range. Power derating with temperature is provided. The part is designed for reliable RF termination in 75 Ohm systems requiring low VSWR up to 1 GHz.
