This is a field-assembly kit: the package includes the connector body, a crimp ferrule for the cable braid, and an end cap that dresses the termination. You supply the RG-174A or RG-316 coax and the solder for the centre pin. ## Cable fit and termination details The connector accepts RG-174A and RG-316 cable groups. Gold body finish on a brass shell resists corrosion in lab or light-industrial environments. ## RF performance that matters for the link budget Rated at 50 Ohms nominal impedance and 4 GHz maximum frequency. The 0.6 dB insertion loss is a single-connector figure. 500 mating cycles is typical for an SMB snap-on interface — the spring fingers in the female socket wear gradually. For a test-point connector that gets cycled daily, that's a couple of years of service before the contact resistance drifts. For a permanent install, it's effectively lifetime.","metaTitle":"TE Greenpar 1-1337478-0 SMB Plug, 50 Ohm, 4 GHz","metaDescription":"TE Connectivity Greenpar SMB plug, female socket, 50 Ohm, 4 GHz max, 0.6 dB insertion loss.
