Description
TNC Plug (Male) to SMA Jack (Female) Adapter | Straight Design | Screw-Lock | Mixed Brass & Stainless Steel Body
The ROSNOL AD-PCT1A25A/9XX-91 delivers outstanding RF performance for applications up to 18 GHz. With a 50 Ω impedance, VSWR ≤ 1.25, and insertion loss ≤ 0.05√f (GHz) dB, this adapter ensures low signal attenuation and high reliability. The screw-lock coupling mechanism provides secure engagement, supported by a center contact captivation ≥27 N and mechanical durability of at least 500 mating cycles. Recommended torque ranges from 0.46 Nm to 0.69 Nm for the TNC side and 0.8 Nm to 1.1 Nm for the SMA side.Material construction includes beryllium copper center contacts with gold plating over nickel-phosphorus underplating for superior conductivity. The TNC body and coupling nut are stainless steel with passivation, while the SMA body is brass with gold plating for enhanced corrosion resistance. PTFE insulators ensure excellent dielectric performance. The adapter operates reliably across a temperature range of -55°C to +100°C.
ROSNOL’s precision RF adapters are manufactured in ISO 9001-certified facilities and comply with RoHS and REACH standards. Designed as cost-effective alternatives to leading global brands, ROSNOL products combine high quality with competitive pricing. Customization services for materials, plating, and mechanical design are available to meet specialized requirements.
