M20-139030V0446

Overview

The Harwin M20-139030V0446 is a vertical pin header from the M20 series, designed for board-to-board or cable connections. It features a 2.54 mm pitch and offers four positions in a single row. The connector utilizes tin-plated contacts with a nylon housing and supports through-hole solder termination. Rated for up to 800 V, it operates within a temperature range of -40°C to +105°C. This component provides reliable electrical interconnection with standard mating pin heights.

Feature Summary

Vertical orientation for direct board mounting
Tin-plated phosphor bronze contacts for conductivity
Nylon insulation housing for durability
Through-hole solder termination style

Applications

Board-to-board interconnections
Cable-to-board wiring harnesses
General electronic equipment signal routing

Procurement Notes

Verify the specific voltage rating of 800 V against application requirements, as this exceeds standard low-voltage norms. Confirm that the vertical form factor aligns with PCB layout constraints. Ensure compatibility with mating connectors using standard 2.54 mm pitch interfaces. Check for RoHS compliance documentation prior to final procurement decisions.

Selection Notes

Select this part when high voltage isolation is required alongside standard 2.54 mm spacing. The vertical design suits applications needing minimal profile height increase. Consider the tin plating for general-purpose use rather than harsh environments requiring gold. Verify that the four-position count matches circuit requirements without excess unused pins.

Part Context

This component belongs to the Harwin M20 series, known for versatile through-hole headers. The M20 line typically includes various row counts and orientations. The M20-139030V0446 specifically addresses needs for higher voltage ratings compared to standard low-voltage variants in the same family.
