The Micro-Fit 3.0™ is a unique interconnect system designed to meet the need for a high contact density signal or power connector and incorporates many of the features previously found on larger power connectors. These 3.00mm (.118" pitch) connectors are the perfect choice when you need compact connectors that carry up to 5 amperes of current. Micro-Fit products are available in circuit sizes 2 to 24 for single and dual row, wire-to-board and wire-to-wire applications. The product family has over 500 part numbers, with many retention choices including fitting nails, solderable clips, and offset terminal retention.

The Micro-Fit 3.0, CPI™ and Micro-Fit 3.0, BMI™ CPI are compliant pin interface vertical header product extensions to this well known Micro-Fit family. These products are designed for high-density applications which require press-fit headers. The CPI products are appropriate for both power and signal uses as they can carry up to 5A per circuit.
