It is a board-to-wire interconnect, designed for applications in automotive, industrial, medical, and telecom equipment where a compact, high-current connection is needed. The header is shrouded on all four walls and uses a locking ramp for secure mating in environments subject to vibration. ## Key Ratings and What They Mean for Your Design Rated 8 A per circuit at 600 V, this header carries enough current for a moderate-power rail or multiple signal lines without needing a larger connector. The 3.00 mm pitch provides adequate creepage distance for the 600 V rating while keeping the board footprint compact. Tin plating on both the mating and post surfaces (60.0 µin) is a cost-effective choice for applications with a moderate number of mating cycles; it is well-suited for internal harness connections where the connector is mated during assembly and rarely disconnected in the field. ## Mechanical and Environmental Fit The through-hole, kinked-pin termination provides a robust solder joint that resists shear forces from cable strain. The locking ramp and 4-wall shroud protect the contacts and prevent accidental unmating.","metaTitle":"Molex Micro-Fit 3.0 0430450483 Header, 4 Pos, 8 A","metaDescription":"Molex Micro-Fit 3.0 header, 4 circuits, dual-row, 3.00 mm pitch, 8 A, 600 V.
