D01-9920401 – HARWIN

The D01-9920401 from HARWIN is a four-position, single-row, vertical PCB-mount header strip. It features a 2.54mm (0.1 inch) pitch, conforming to industry-standard spacing for mating connectors. The insulator material is typically glass-filled polyester (PBT or similar) providing high temperature resistance suitable for reflow soldering processes, with a flammability rating of UL94V-0. Contact material is commonly gold-plated brass or phosphor bronze, ensuring reliable electrical connection and corrosion resistance. The gold plating thickness is typically specified to meet performance requirements for insertion cycles and environmental conditions. The header is designed for through-hole mounting, providing a robust mechanical connection to the printed circuit board. Current rating is dependent on the specific contact material and plating, but typically ranges from 3A per contact. Operating temperature range is generally -40°C to +105°C.
