Miniature 75
Ω
SMB
Resistive Termination
This miniature 75Ω SMB resistive termination features a Teflon insulator for greater ruggedness than similar
air-dielectric designs. The insulator is colored red for visual identification of its 75Ω impedance.
The closed-entry center contact and mating end hood provide further resistance to damage in case of
misalignment during mating.
Other resistance values are also available—contact factory for more information.
