M50-4903545

Headers, Male Pins Overview

The M50-4903545 is a surface-mount header from the Harwin Archer M50 series, featuring a 1.27 mm pitch and 70 positions in a dual-in-line configuration. It utilizes gold-plated phosphor bronze contacts housed in black liquid crystal polymer (LCP) insulation. The component supports a maximum current of 1 A and operates within a temperature range of -40°C to +105°C. Designed for SMD/SMT installation with straight pin orientation, it offers high insulation resistance and UL 94 V-0 flammability rating.

Headers, Male Pins Feature Summary

• Dual-row shrouded design ensures precise alignment during board-to-board or wire-to-board connections.
• Gold-plated contacts provide reliable signal transmission and corrosion resistance.
• Liquid crystal polymer housing delivers high thermal stability and mechanical strength.

Headers, Male Pins Applications

• High-density electronic assemblies requiring compact interconnects
• Board-to-board communication links in consumer electronics
