BNC Plug for RG-55/223 — Kit Includes Contact and Ferrule
The 225395-3: This plug is built for RG-55, RG-55A, RG-55B, and RG-223 cable — the common double-shielded 50 Ohm coax types used in instrumentation and low-power RF.
RF Performance and Mating Life
The 500 mating cycles mean it will survive daily reconnections on a test bench for years before the gold-on-brass centre contact shows wear. The 500 V voltage rating covers the peak levels you'd see in 50 Ohm test equipment and most RF amplifier stages; the limiting factor at higher frequencies is the connector's VSWR, not the dielectric breakdown.
