142-1701-636 is a 2-hole flange-mount SMA jack connector designed for field-replaceable RF and microwave applications. The connector features a brass body with nickel plating over copper, beryllium copper contacts with gold plating, and a Teflon insulator, providing excellent electrical and mechanical performance. It operates across a frequency range of 0–26.5 GHz with 50-ohm impedance, supporting a working voltage of 335 VRMS maximum and dielectric withstanding voltage of 1000 VRMS minimum. The connector accepts a 0.020" diameter pin to a maximum depth of 0.110 inches and is rated for 500 durability cycles minimum. Its robust construction and environmental compliance (MIL-STD-202 standards) make it suitable for demanding aerospace, defense, and telecommunications equipment requiring reliable high-frequency signal transmission.
