Shrouded on all four walls with a locking ramp fastening type: mates with the receptacle and locks audibly. Board-to-cable/wire style: the header solders to the PCB, the receptacle crimps onto the wire. Rated 600 V, temperature range -40°C to 105°C, UL94 V-0 housing. ## SMT termination with solder retention Tin-plated mating contacts at 60.0 µinch thickness — rated for moderate mating cycles. In a field-service application cycled quarterly, the contact interface holds up well past a decade of service. Brass alloy contact material. No official successor or cross-reference from Molex; the 043045 base number covers the series. ## Where it goes — automotive, industrial, medical, telecom Applications listed include Automotive, General Purpose, Industrial, Medical, and Telecommunications. The locking ramp and 105°C rating suit under-hood and cabinet environments where connectors see thermal cycling and vibration.","metaTitle":"Molex 0430451018 Micro-Fit 3.0 Header, 10 Pos, 3mm Pitch","metaDescription":"Molex 0430451018 Micro-Fit 3.0 43045 series header, 10 circuits, 3.00mm pitch, shrouded SMT with locking ramp.
