Frequently Asked Questions
What contact plating does the MLE-109-01-G-DV-A use, and how does gold plating improve connector reliability?
The MLE-109-01-G-DV-A uses 10 µin gold over 50 µin nickel on both mating and termination contacts. Gold plating provides excellent corrosion resistance and maintains low contact resistance below 20 mΩ over thousands of mating cycles, making it preferable for high-reliability board-to-board connections in defense and test equipment.
What are the physical dimensions of the MLE-109-01-G-DV-A, and how does its compact size benefit high-density designs?
The connector body measures 0.322 inch long, 0.13 inch deep, and 0.121 inch wide, occupying a very compact footprint. This small size allows designers to place multiple 9-position connectors in a small PCB area, supporting high-pin-count board-to-board interconnect configurations in space-constrained modules with pitch spacing below 1 mm.
Which application areas favor the MLE-109-01-G-DV-A over tin-plated alternatives for board interconnect?
Defense, aerospace, and high-frequency test equipment applications favor the MLE-109-01-G-DV-A over tin-plated connectors because gold contacts resist fretting corrosion at low signal levels below 100 mV and maintain stable 50-Ω impedance paths at frequencies up to several GHz, where tin contacts degrade over time due to oxide formation.
