The Micro-Fit Connector System offers 8.5A with a 3.00mm pitch, delivering power in a compact package. Available for wire-to-wire and wire-to-board configurations, the Micro-Fit Power Connector is suitable for a wide range of applications including automotive, consumer electronics, medical devices, sustainable energy and telecommunications and networking.


Customers often need power connectors in space-constrained applications, the Micro-Fit 3.0 Power Product Family from Molex meets this need. Available in multiple circuit sizes and cable lengths for power and signal applications, there is a Micro-Fit product to solve any challenge. Micro-Fit 3.0 BMI Connectors are designed for blind-mating in hard-to-reach applications, such as drawers or fan assembly trays, as the connectors can be mated and unmated without being seen. The Micro-Fit 3.0 TPA Receptacle helps prevent failure in end products by offering terminal position assurance (TPA). The integrated TPA reduces terminal back-out by providing locking redundancy. For example, assemblers cannot insert the TPA unless the terminal is properly inserted. Micro-Fit 3.0 CPI (Compliant Pin) Connectors provide a compliant pin interface while maintaining all the features of the standard Micro-Fit Connector. The robust eye-of-the-needle design provides a reliable interface when recommended board layouts are followed. The Micro-Fit 3.0 CPI Header mates with Micro-Fit 3.0 Receptacle, allowing running changes as boards transition from solder to press-fit applications. Micro-Fit 3.0 RMF (Reduced Mating Force) Terminals are designed for applications needing lower engagement and disengagement forces or when the units are cycled frequently. The pre-lubricated version can be mated up to 250 times and fit into standard Micro-Fit 3.0 Housings.
