R125251000

The Radiall R125251000 is an SMA straight 2-hole flange jack solder connector designed for use with RG-402 (.141" semi-rigid) coaxial cable. This connector provides a 50 Ohm impedance and operates from DC to 18 GHz, making it suitable for high-frequency RF applications. The connector features a threaded coupling for secure mating and a solder termination for both center contact and shield. The body is made of stainless steel with gold plating (0.5 µm over nickel 2 µm), and the center contact is beryllium copper with gold plating (1.3 µm over nickel 2 µm). The insulator is PTFE. Electrical performance includes a maximum VSWR of 1.05 + 0.008 x F(GHz), insertion loss of 0.03 √F(GHz) dB, and RF leakage of -(90 - F(GHz)) dB. The connector is rated for 500 Veff maximum voltage and has a dielectric withstanding voltage of 1000 Veff minimum. Insulation resistance is 5000 MΩ minimum. Mechanically, the connector is panel mounted with a flange, and has a mating life of 500 cycles minimum. Operating temperature range is -65 to +105 °C. The connector weighs 1.890 g. Standard packaging is 100 pieces per unit, with a 'W' option available upon request. This connector is ideal for applications requiring reliable RF connections in test equipment, telecommunications, and aerospace systems.
