This fully shrouded header features tin-plated brass contacts, PCB polarizing pegs, and kinked solder pins for secure board retention. With a 5A typical current rating (8.5A max) and 600V voltage rating, it provides reliable wire-to-board power distribution in a compact footprint.","working_principle":"The Micro-Fit 3.0 header employs a positive locking ramp mechanism that engages with the mating receptacle housing to prevent accidental disconnection under vibration and shock. The fully shrouded 4-wall housing design protects the dual-beam contacts from damage during handling and mating. The tin-plated brass contacts provide four points of contact per mating interface for redundant electrical connection. The kinked solder pins ensure mechanical retention to the PCB during wave soldering, while the PCB pegs provide accurate positioning and polarization.","pin_description":"
