SMA Jack (Female) | Soldered Cable Entry | Screw-lock | Stainless Steel Body | Sealing

The ROSNOL SMA2EA50-0141D/9Q is a bulkhead-mount SMA jack designed for solder attachment to .141 cables, supporting 50Ω RF systems from DC to 18 GHz. Featuring a screw-lock coupling mechanism and soldered cable entry, the connector ensures stable signal transmission. The soldered centre contact delivers excellent electrical performance with VSWR ≤ 1.25 (≥ 19.08 dB), insertion loss ≤ 0.03 × √F (GHz) dB, insulation resistance ≥ 5 GΩ, and RF leakage ≥ 100 dB up to 1 GHz. Power handling reaches 200 W @ 2 GHz under optimal conditions.

The connector body is stainless steel with gold plating over non-magnetic nickel-phosphorus, while the centre contact is beryllium copper with matching plating. The insulator is PTFE, and the coupling nut and washer are brass with gold plating. Designed for ≥ 500 mating cycles, it operates reliably from -65°C to +165°C and meets MIL-STD standards for thermal shock, corrosion, vibration, shock, and moisture resistance.

Compatible cable types include RSR141, RSF141, RSF141-FEP, UT 141, RG402/U, RTK-FS 141, RTK-Flex 402, and Belden1673A, offering broad integration flexibility for high-frequency applications.
