The body is zinc die cast with a tin finish, and the housing is green, which is the standard colour for the Fakra Code E keying variant. This variant ensures it only mates with a Code E receptacle, so you don't accidentally cross-connect different RF lines in a harness. ## 50 Ohm at 3 GHz — The RF Path The 3 GHz max frequency covers the common sub-3 GHz bands. ## Through-Hole Mount, Solder Termination This plug mounts through-hole and terminates both the centre pin and the shield with solder. The shield termination is solder, not a crimp ferrule, so you'll need a soldering iron and a steady hand — not a crimp tool. The body is zinc die cast with a tin finish, which solders well but doesn't offer the corrosion resistance of a stainless or nickel-plated body if the connector lives in a salt-spray zone. For that, you'd want a different Fakra variant.","metaTitle":"Amphenol 2FA1-NESP-PCBB6 SMB Fakra Plug, 50 Ohm, 3 GHz","metaDescription":"Amphenol 2FA1-NESP-PCBB6 SMB Fakra plug, male pin, 50 Ohm impedance, 3 GHz max frequency, through-hole, locking ramp.
