Product details

MMCX-LR-SMT — Hirose MMCX Receptacle for Board-Edge RF

The Hirose MMCX-LR-SMT is a 50 Ohm MMCX receptacle, female socket, designed for board-edge cutout mounting with surface-mount terminations. It belongs to the MMCX series of subminiature push-on RF connectors, specified for snap-on fastening and rated to 6 GHz. The gold-plated beryllium copper centre contact and gold body finish are standard for maintaining signal integrity through repeated matings — the 500-cycle rating covers field-service reconnects without contact degradation.

Mounting and Footprint Notes

This receptacle mounts to a board-edge cutout with surface-mount solder pads — not a standard through-hole or SMT-only footprint. The board-edge cutout means the connector body sits partly off the board edge, which affects the ground-plane keep-out zone. Layout engineers should verify the cutout dimensions against the Hirose product drawing before committing the PCB.

Compatibility with Standard MMCX Cables

The snap-on fastening and 50 Ohm impedance are standard MMCX interface dimensions, so this receptacle mates with any standard MMCX plug that follows the interface specification.

Frequently asked questions

Where can I buy the MMCX-LR-SMT?

The MMCX-LR-SMT is obsolete and sourced through the surplus and broker channel. It is quoted to order against an RFQ — availability and current pricing are confirmed at quote time through independent distribution.

What is the impedance of the MMCX-LR-SMT?

The MMCX-LR-SMT is a 50 Ohm impedance connector, rated to 6 GHz maximum frequency. The 50 Ohm controlled-impedance design matches standard RF transmission lines and MMCX cable assemblies.
