Description

Dummy load resistor. 8 ohm 100 W non-inductive.

Ohmite mfg. Co., Chicago.
The D100 (100W) and D250 (250W) RF resistors were available in 13 resistance values, from 8 to 600 ohms. Distributed capacitance was around 5pF, while residual inductance was between 0.1 and 1 microhenries, depending upon resistance value. Max operating frequency ranges from 40MHz for the 13 ohms type to 5MHz for the 600 ohms.
