* Resistive Terminations
These miniature resistive terminations exhibit 75 W impedance for critical applications, with envelope dimensions conforming to the size of MIL-PRF-39012 SMB series connectors. They have convenient snap-on mating and their small size make them ideal for use in applications that require dense packaging. The terminations feature Teflon insulators that protect the center contacts from damage if they are misaligned during mating. The use of a precise (±1 percent tolerance) 75 W rod resistor enables the terminations to dissipate one full watt of power at normal ambient temperature, derating to 100 mW at 125°C. The terminations are constructed with tempered brass bodies and beryllium copper closed-entry female center contacts.
