SMB jack for RG-174/188/316 — 50 Ohm, 4 GHz signal path
The TE Connectivity 5228217-1 is an SMB jack with a male pin centre contact, designed for 50 Ohm impedance and rated to 4 GHz. The kit includes 5 pieces: the connector body, one contact, one ferrule, one lockwasher, and one nut — everything needed for a single cable termination. The centre contact is brass with gold plating, and the body has a nickel finish.
Cable compatibility and field termination
This connector is specified for cable groups RG-174, RG-188, and RG-316 — 50 Ohm coax types. The crimp termination for both centre contact and shield makes it field-serviceable.
Insertion loss and voltage rating
Insertion loss is specified at 0.3 dB — a tight figure that keeps signal degradation low through the connector interface. The voltage rating is 335 V, which is generous for a 50 Ohm RF connector and gives headroom in applications where DC bias or power-over-coax is present on the same line.
