M20-8770442R

Headers, Male Pins Overview

The M20-8770442R is a Harwin M20 series single-row male pin header designed for surface mount technology. It features a 2.54 mm pitch and provides four positions for board-to-board or wire-to-board connections. The connector utilizes brass contacts with gold plating to ensure reliable signal transmission. Constructed with a nylon insulation body, it supports a rated current of 3A per contact and operates within a temperature range of -40°C to 105°C. The straight orientation facilitates vertical mounting on printed circuit boards.

Headers, Male Pins Procurement Notes

Verify the specific suffix 'R' against official Harwin documentation to confirm reel packaging requirements. Ensure compatibility with standard SMT reflow profiles. Confirm that the 4-position configuration matches the target circuit design before procurement. Cross-reference the datasheet for precise mechanical dimensions and soldering recommendations.

Headers, Male Pins Selection Notes

Select this component when a low-profile, single-row surface mount header is required. The 2.54 mm pitch is standard for general-purpose electronics. Consider the 3A current rating and 105°C temperature limit for thermal management. Verify that the straight pin orientation fits the spatial constraints of the assembly.
