It is a surface-mount connector with threaded fastening, part of the 73251 series. The 50 Ohm impedance matches standard 50 Ohm transmission lines, and the 18 GHz maximum frequency covers the full SMA band — suitable for microwave test equipment, antenna feeds, and RF module I/O where the signal integrity through the launch matters. The brass body carries a nickel finish. Dielectric is PTFE, which keeps insertion loss low across the band. The 18 GHz bandwidth means this jack handles the full SMA frequency range; above that, mode propagation in the dielectric starts to degrade the signal. Surface-mount termination suits automated pick-and-place and reflow assembly, but the SMT pad footprint must be designed to maintain the 50 Ohm impedance through the transition from microstrip to the connector launch. Threaded fastening gives a vibration-resistant mate, which matters when the cable is field-handled or the assembly sees mechanical shock.","metaTitle":"Molex 0732511353 SMA Jack, 50 Ohm, 18 GHz, SMT","metaDescription":"Molex 0732511353 SMA jack, 50 Ohm impedance, 18 GHz max frequency, surface mount, gold-plated beryllium copper center contact.
