The contact terminates by crimp or solder; the shield crimps over the ferrule. The PTFE dielectric handles the temperature range and keeps impedance stable through the termination. If you're working with RG-316, this plug is a direct fit. ## Cross-Shop: 415218-1 as a Functional Alternative If 413985-4 is on allocation, the 415218-1 is a direct functional peer — same SMB plug, female socket, 50 Ohm, bulk package, active lifecycle. The key difference is the cable group: 415218-1 may target a different cable type. Confirm your cable fit before swapping.","metaTitle":"TE Connectivity 413985-4 SMB Plug, 50 Ohm, 4 GHz","metaDescription":"TE Connectivity 413985-4 SMB plug, female socket, 50 Ohm impedance, 4 GHz max, 0.3 dB insertion loss.
