BNC Plug (Male) to TNC Plug (Male) Adapter, DC-4.0 GHz VSWR 1.35

BNC Plug (Male) to TNC Plug (Male) | Straight Design | Bayonet-Lock & Screw-Lock | Brass Body

Product code: AD-B1T15A/933-933. This ROSNOL 50 Ω adapter covers DC to 4 GHz with VSWR ≤ 1.35 (≥ 16.54 dB return loss) and insertion loss ≤ 0.05 × √F (GHz) dB, enabling consistent signal integrity. Electrical ratings include 1500 Vrms test voltage, 400 Vrms working voltage, and ≤ 80 W power handling at 2 GHz. The BNC side uses bayonet-lock while the TNC side uses screw-lock for reliable coupling. Mechanical durability is ≥ 500 mating cycles, axial center-contact captivation ≥ 15 N, and TNC recommended torque 0.46–0.69 N·m.

Materials and plating stack: beryllium copper center contacts with 3 µin gold over 80 µin non‑magnetic nickel‑phosphorus underplating; brass bodies and coupling nuts with nickel plating; PTFE insulators; silicone rubber gaskets. The nickel-over-brass construction enhances corrosion resistance, with an operating temperature range of −65 °C to +165 °C.
