Description
The MMCX (Micro-Miniature Coaxial) female connector is a high-performance RF component valued for its exceptionally small footprint and its ability to provide a secure, rotatable connection in space-constrained environments. This variant is specialized for the 2.5mm to 3mm cable class, specifically optimized for high-performance LMR100 and high-temperature RG316. The snap-on coupling mechanism allows for quick mating with MMCX plugs, facilitating rapid assembly in complex electronic systems.
As a female interface (jack), it features a precision-machined internal contact sleeve designed to accept the center pin of MMCX male connectors. This connector utilizes a hex-crimp termination system for the outer conductor, providing a high-strength mechanical bond and excellent strain relief for flexible coaxial lines. Manufactured with a gold-plated brass body and premium PTFE (Teflon) insulation, it delivers consistent 50-Ohm performance and reliable operation up to 6 GHz, ensuring signal integrity in sophisticated IoT, broadband, and medical devices.
Key Technical Advantages
-
Micro-Miniature Snap-On Design: The ultra-compact interface enables high-density packaging on PCBs and within small enclosures where traditional threaded connectors are too bulky.
-
Thin-Gauge Cable Match: Specifically calibrated for the 0.100″ to 0.110″ OD cable family, ensuring a precise mechanical fit and optimized electrical transition for LMR100 and RG316 lines.
