The Mini-Fit Family is designed for higher-current/higher-density applications which require design flexibility for wire-to-wire, wire-to-board and board-to-board configurations. Mini-Fit products are ideal for power applications up to 13A per circuit.
The core attributes of the Mini-Fit family include: an operating temperature of -40°C to +105°C, fully isolated terminals, positive housing locks, low-engagement forces and polarised housings and receptacles. Mini-Fit products are UL recognised and CSA approved. All components are lead-free and RoHS compliant.
The family includes:

Mini-Fit Jr. connectors handle up to 9A and are ideal for wire-to-wire and wire-to-board applications requiring design flexibility.
The core attributes of Mini-Fit Jr. include: fully isolated terminals, positive locking housings, low-engagement forces and polarized housings. The Mini-Fit family also offers blind mating, TPA and higher current options.
Designed for higher-current, higher-density applications requiring design flexibility, Mini-Fit Jr. connectors are ideal for power applications up to 9A per circuit. Additionally, these connectors are available in single row or dual row 2- to 24-circuit options, feature multiple plating, and resin options.
Mini-Fit Blind Mate Interface (BMI) connectors support up to 13A for high-current and high-density applications in wire-to-wire, wire-to-board and board-to-board applications.
Mini-Fit BMI connectors allow misalignment and provide "float" of up to 2.54mm between mating surfaces for easy blind-mate connections. In addition, the connectors utilise both the Mini-Fit Jr. and high current Mini-Fit Plus female and male crimp terminals to support up to 9A or 13A.
Mini-Fit BMI panel-mount receptacles are designed to float or self-align. The headers and plugs feature flanges that help to "gather" the mating receptacle. Many options are offered including: through-hole, press-fit or SMC headers; tin or gold terminals; and multiple resin options to support the changing needs of manufacturing.
Mini-Fit TPA plugs and receptacles handle up to 13A and are ideal for high-current applications requiring a redundant terminal retention feature.
Mini-Fit TPA plugs and receptacles utilise a highly visible "TPA pin" that indicates when a terminal is fully seated in the housing and ensures that the terminal will not back out of the housing during mating or when in use. Mini-Fit TPA connectors feature a Connector Position Assurance (CPA) key, ensuring that the male and female connectors cannot be accidentally disengaged. The Mini-Fit TPA product family accepts all standard Mini-Fit crimp terminals, further reducing design and qualification efforts. Mini-Fit TPA products are available in wire-to-wire and wire-to-board configurations, with various circuit sizes ranging from 2- to 16-position accommodating 16AWG to 28AWG.
Delivering up to 13A, the Mini-Fit Plus 4.20mm pitch connector system increases power delivery for high-current applications in virtually any industry without increasing design footprints.
The Mini-Fit Plus system offers a high-current, power-dense, mid-range power connection system. The Mini-Fit Plus system leverages the same housings, PCB footprint and application tooling as Mini-Fit Jr. and Mini-Fit BMI systems.
With the launch of the Mini-Fit Plus high-conductive terminal, customers can increase power carrying capabilities while leveraging the extensive Mini-Fit Jr. product portfolio.
The Mini-Fit Plus system consists of crimp terminals, headers and PCB receptacles; 13A per circuit can be achieved using 16AWG wire. Mini-Fit Plus terminals can be used with all existing Mini-Fit plug and receptacle housings. In addition, all standard Mini-Fit right-angle headers are inherently Mini-Fit Plus compatible, as they feature a solid-pin construction which is designed to handle high current.
