The 43045-2026 from Molex is a 20-circuit Micro-Fit 3.0 PCB header connector in a right-angle (90\u00b0) surface-mount configuration. Featuring dual-row design with 3.00mm pitch, it supports up to 8.5A per contact and 600V rated voltage. The connector uses tin-plated brass contacts in a high-temperature thermoplastic housing, suitable for wire-to-board power and signal applications requiring moderate contact density with higher current capacity.<\/p>\n

The dual-row right-angle surface-mount configuration with 3.00mm pitch provides a compact solution for moderate-density connections. 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 and corrosion resistance, while the high-temperature thermoplastic housing (UL E29179) withstands lead-free reflow soldering profiles and operates continuously up to 105\u00b0C.","working_principle":"1. Contact Interface: The header features 20 tin-plated brass contacts arranged in a 10x2 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 with positive retention.\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.\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 distances for 600V rated voltage.\n4. Housing Protection: The covered (shrouded) high-temperature thermoplastic housing provides electrical insulation between contacts and mechanical protection against handling damage during mating and unmating operations.","pin_description":"
