SMC M SOLDER? for Semi-rigid .141/RG402 Cable

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

• Fused Solder Termination: The direct-solder design for both the center conductor and outer jacket ensures maximum electrical continuity and the lowest possible signal leakage at microwave frequencies.

• RG402 / .141 Precision Engineering: Specifically calibrated for the dimensions of 0.141-inch semi-rigid and hand-formable cables, ensuring perfect 50-Ohm impedance matching.

• Threaded Vibration Security: The #10-32 threaded interface provides a secure mechanical lock, preventing accidental decoupling and signal jitter in high-vibration aerospace and industrial applications.

• Microwave Frequency Range: Optimized to support stable signal transmission up to 10 GHz, suitable for high-speed data links, GPS, and X-band radar modules.

• Superior Corrosion Protection: High-grade gold-over-nickel plating on the body and contact surfaces ensures low contact resistance and long-term durability in demanding environments.

Key Features

• Interface Type: SMC Male (Plug) with 50-Ohm threaded interface.

• Cable Compatibility: Optimized for .141″ Semi-Rigid, RG402, and .141-inch Conformable coaxial cables.
