The PTFE dielectric withstands soldering temperatures without melting or shifting, a practical concern when hand-soldering the center pin. ## Single-Port, Bulk Packaging This is a single-port jack, supplied in bulk packaging — loose pieces in a bag or box, not tape-and-reel. For low-volume builds or prototype runs, bulk is straightforward; for high-volume pick-and-place, the right-angle through-hole format is typically hand-placed or wave-soldered anyway. ## Active Lifecycle — Sourced to Order","metaTitle":"Amphenol RF 142146-75 SMB Jack, 75 Ohm, Right Angle","metaDescription":"Amphenol RF 142146-75 SMB mini jack, male pin, 75 Ohm impedance, right-angle through-hole, gold body, 500 mating cycles, -65°C to 165°C.
