R125078000 Description

Short technical summary and product information.

The Radiall R125078000 is an SMA straight plug connector with a male pin contact. It supports both crimp and solder termination styles, making it versatile for cable assembly. The connector is designed for use with RG-142, RG-223, and RG-400 cables, providing a reliable 50 Ohm impedance match for RF applications up to 12.4 GHz.

Key electrical characteristics include a maximum VSWR of 1.15 + 0.010 x F(GHz), insertion loss of 0.06 √F(GHz) dB, and RF leakage of -(60 - F(GHz)) dB. The voltage rating is 335 Veff maximum, with a dielectric withstanding voltage of 1000 Veff minimum and insulation resistance of 5000 MΩ minimum.

Mechanically, the connector features a stainless steel body, gold-plated brass center contact (1.3 µm gold over 2 µm nickel), and gold-plated outer contact. The PTFE insulator ensures stable performance across the operating temperature range of -65°C to +165°C. Recommended mating torque is 100 N.cm, and the connector is rated for a minimum of 500 mating cycles.
