The SMC interface uses a threaded coupling (M7 x 0.75) for a vibration-resistant mate, smaller than an SMA but larger than an SMB. ## Why 75 Ohm Matters — Don't Mistake It for a 50 Ohm Part Most RF connectors in this form factor — SMA, SMB, SMC — are 50 Ohm. The 152107-75 is explicitly 75 Ohm, which means it's intended for video, broadcast, or data-comm applications where the system impedance is 75 Ohm (e.g., CCTV, baseband video, or RF over coax at lower frequencies). Mating it with a 50 Ohm cable or a 50 Ohm jack will create an impedance mismatch that shows up as return loss and signal degradation. The cable group — RG-174, 188, 188A, 316, LMR-100, M17/119-RG174 — are all 50 Ohm cables, but the connector's internal geometry is tuned for 75 Ohm. The insertion loss is 0.6 dB, which is typical for a right-angle SMC plug at lower frequencies (likely under 4 GHz, though the datasheet does not state a max frequency for this variant). ## Termination and Cable Prep — What You Get in the Kit The kit includes four pieces: the connector body (with the centre contact pre-installed), an end cap that threads over the cable jacket, a crimp ferrule for the braid, and a heat shrink tube to seal the cable entry.","metaTitle":"152107-75 Amphenol RF SMC Plug, 75 Ohm, RG-174 Cable","metaDescription":"152107-75 Amphenol RF SMC plug, 75 Ohm, for RG-174/316/LMR-100.
