With up to 8.5A per contact and a 600V voltage rating, this header provides reliable power delivery in a space-efficient single-row format. The kinked solder pins and PCB polarizing pegs ensure secure board attachment and accurate assembly placement.","working_principle":"The Micro-Fit 3.0 43650-0419 header uses the standard Micro-Fit positive locking ramp mechanism that engages with the mating receptacle housing to prevent accidental disconnection. The fully isolated dual-beam contacts provide four points of contact per mating interface, ensuring reliable power delivery with low contact resistance. The kinked through-hole pins provide mechanical retention to the PCB during wave soldering, while the LCP housing tolerates lead-free IR reflow temperatures up to 265\u00b0C.","pin_description":"
