SSMB-KWHD is a miniature SSMB female RF coaxial connector designed for PCB through-hole soldering assembly. It adopts compact SSMB quick snap-on mating structure, supporting stable signal transmission from DC to 4.0 GHz with VSWR ≤1.25. Gold-plated brass housing delivers excellent shielding performance and corrosion resistance. The contact pin is made of gold-plated beryllium-copper or brass, offering stable contact performance after repeated plugging. Teflon insulator ensures low dielectric loss. Its ultra-small footprint is ideal for space-limited PCB wireless modules and portable electronic equipment.
