The dual-row, right-angle surface-mount configuration with 3.00mm pitch provides a compact solution for moderate-density connections requiring higher current capacity. Each contact supports up to 8.5A and 600V, making it suitable for power distribution in computer, telecommunications, and industrial equipment. The tin-plated brass contacts ensure reliable solderability, while the high-temperature thermoplastic housing withstands reflow soldering profiles and operates continuously up to 105\u00b0C.","working_principle":"1. Contact Interface: The header features 14 tin-plated brass contacts arranged in a 7x2 dual-row configuration at 3.00mm pitch. The contacts mate with corresponding female terminals in the Molex Micro-Fit 3.0 receptacle housing, creating a separable connection.\n2. SMT Attachment: The right-angle surface-mount design positions the mating interface parallel to the PCB surface. Solder pads on the bottom of the connector provide both electrical connection and mechanical retention to the PCB.\n3. Current Carrying: The brass contact material and sufficient contact cross-section support 8.5A continuous current per contact. The 3.00mm pitch provides adequate creepage and clearance for 600V rated voltage.\n4. Housing Design: The high-temperature thermoplastic housing provides electrical insulation between contacts and mechanical protection. The covered (shrouded) design prevents contact damage during handling and mating.","pin_description":"
