The kit format means you don't have to source the contact and ferrule separately for a single repair or prototype run. ## SMB vs BNC — Interface Difference This is an SMB connector, not a BNC. The snap-on coupling is smaller and faster than a BNC's bayonet lock, and the SMB interface is rated to 4 GHz versus a typical BNC's 1-2 GHz limit. The trade-off is lower mating cycle life — 500 cycles here against a BNC's typical 500-1000 — and no 75-ohm variant in this series. If your system calls for BNC, the 413985-3 will not mate.","metaTitle":"TE Connectivity 413985-3 SMB Plug, 50 Ohm, 4 GHz","metaDescription":"TE Connectivity 413985-3 SMB plug, female socket, 50 Ohm impedance, 4 GHz max, for RG-174/188/316 cable.
