Molex Micro-Fit 3.0 Series Straight Surface Mount PCB Header, 4 Contact(s), 3.0mm Pitch, 2 Row(s), Shrouded

Micro-Fit 3.0 3mm pitch wire to board SMT headers which form part of a compact power connector system providing a low to mid-range power distribution solution. With the ability to carry up to 5A of current, Micro-Fit 3.0 connectors have one of the highest current carrying abilities in the smallest footprints available. These Micro-Fit 3.0 PCB headers incorporate positive latching in the form of a locking ramp on the housing for secure mating and to prevent accidental disconnection. The housings are made of high-temperature UL 94V-0 Liquid Crystal Polymer that can withstand temperatures of up to 265°C during the IR reflow soldering process. To secure these Micro-Fit 3.0 SMT headers to the PCB board, solder tabs are incorporated into the connector design. The contacts of these Micro-Fit 3.0 headers are fully isolated within the housings to reduce arcing. Tin or a choice of two thicknesses of gold contact platings are available to keep down costs.

• High current carrying capacity in a small footprint
• High temperature housings for IR reflow soldering
• Positive latching for secure mating connection
• Fully isolated dual beam terminals for reliable electrical performance and contact
