TNC Jack, 50 Ohm, 4 GHz — ZDC Greenpar Series
The 5-1814805-1: This female socket connector is specified at 50 Ohms impedance with a maximum operating frequency of 4 GHz, making it suitable for base station, antenna, and test equipment installations where a stable, low-VSWR connection is needed through the lower microwave bands. The through-hole solder termination and nickel-plated zinc body give it a robust, field-serviceable construction.
500 Mating Cycles — Threaded Coupling for Vibration Resistance
The threaded fastening type provides positive mechanical retention under vibration — a key advantage over bayonet-style BNC connectors in mobile or outdoor installations. The gold-plated phosphor bronze centre contact maintains signal integrity across those cycles, resisting corrosion and fretting at the RF interface.
Obsolete — Sourcing Strategy for 5-1814805-1
No direct replacement part number is provided in the lifecycle record. For BOM lines still specifying this exact order code, procurement should plan for last-time-buy coverage or source from surplus and broker channels.
PTFE's low dielectric loss and consistent permittivity help maintain the 50 Ohm characteristic impedance through temperature swings, important for outdoor antenna feeds or equipment enclosures without climate control.
