SMB Snap-On Plug for RG-174/188/316
The 5414363-3: The snap-on fastening type gives a quick, positive lock that holds under vibration without a threaded coupling nut — typical for test equipment, antenna feeds, and short-run RF interconnects where the 50 Ohm system impedance and 3 GHz bandwidth ceiling match the signal path. The nickel-plated zinc body provides RF shielding and environmental protection.
At 3 GHz the specified insertion loss is 0.6 dB, which is typical for an SMB interface at that frequency — the loss is dominated by the cable, not the connector. The 335 V voltage rating is adequate for most RF signal paths; the real limit is the cable's breakdown voltage. Cable compatibility is the first check: this plug accepts RG-174, RG-188, and RG-316 — all 50 Ohm cables with a nominal 0.100-inch diameter over the dielectric. The ferrule and centre contact dimensions are sized for those cable types; using a different cable group will not crimp correctly and will shift the impedance.
