M50-4300645

Headers, Receptacles, Female Sockets Overview

The Harwin M50-4300645 is a surface-mount receptacle connector from the Archer M50 series. It features a 12-position, single-row configuration with a 1.27 mm (0.05 in) pitch. The contacts are female sockets plated with gold, fabricated from phosphor bronze to ensure reliable signal transmission. Designed for vertical installation on printed circuit boards, this component utilizes a solder termination method suitable for automated assembly processes. The housing is constructed from black liquid crystal polymer (LCP), providing high thermal stability and mechanical strength. It operates within a temperature range of -40°C to +105°C and meets UL 94 V-0 flammability standards.

Headers, Receptacles, Female Sockets Procurement Notes

Verify that the specific part number matches the required contact count and row configuration before ordering. Confirm that the surface-mount footprint aligns with the target PCB layout specifications. Ensure compatibility with standard reflow soldering profiles used in your production line. Check for any specific handling requirements related to the moisture sensitivity level of the LCP material. Validate that the voltage and current ratings meet the operational demands of the intended circuit application.

Headers, Receptacles, Female Sockets Selection Notes

Select this component when a low-profile, high-density connection is required for signal-level applications. The 1.27 mm pitch allows for significant pin density within limited board areas. Consider the gold plating for environments where oxidation resistance is critical. The single-row format simplifies routing compared to dual-row alternatives. Evaluate the thermal performance of the LCP material against the operating conditions of the final assembly to ensure long-term reliability.

Headers, Receptacles, Female Sockets Part Context
