Description
The SMC Male (Plug) Solder Type Connector for .141/RG402 is an ultra-stable RF interface built for applications where phase stability and maximum shielding are non-negotiable. Semi-rigid cables like .141 (RG402) are favored in high-frequency microwave systems for their solid copper outer jacket, which provides 100% EMI shielding. This SMC connector is precision-machined to allow the cable’s outer conductor to be soldered directly to the connector body, creating a fused electrical bond that far exceeds the performance of mechanical crimping.
Operating from DC up to 10 GHz, the SMC interface features a threaded #10-32 coupling mechanism. This ensures a secure, vibration-resistant connection that maintains constant contact pressure, making it superior to snap-on alternatives in aerospace and military environments. The connector is manufactured with a gold-plated brass body and premium PTFE (Teflon) insulation, ensuring low VSWR and exceptional thermal stability during the soldering process. Its robust construction is designed to withstand the rigors of high-frequency signal routing in both laboratory and field-deployed microwave assemblies.
Key Technical Advantages
