Introduction
The 4.3-10 female RF coax connector adopts a four-hole flange straight female head structure and directly terminates 250 specification semi-rigid coaxial cable by welding. The industry standard model is often marked as 4.3-10-K-.250", which is specially adapted to RF system scenarios that require high-density installation and low passive intermodulation.
Features
This 4.3-10 female RF coax connector uses solder termination for inner and outer conductors. The construction maintains contact impedance and offers shock resistance. Low PIM design limits torque influence on RF performance and reduces intermodulation interference. The form factor is more compact than traditional 7/16 DIN connectors. It fits high-density wiring inside RF modules and saves internal space. PTFE insulation delivers wideband low-loss characteristics and reduced signal reflection across DC to 6 GHz. This connector is for 0.250-inch semi-rigid coaxial cable. It preserves cable shielding for short patch cords built inside instruments and base station modules.
Connector Design
The 4.3-10-K250 connector combines a 4.3-10 female mating interface with a rear solder termination for the .250 cable.
The 4.3-10 interface provides the equipment-side RF connection, while the rear section is prepared for soldering to the cable conductor and corresponding cable components.
Unlike clamp-type connectors designed for larger feeder cables, this solder configuration is intended for applications where a direct soldered cable termination is preferred.
