Samtec Inc. Header, 2.54Mm, Though Hole Vertical, 44 Position; Connector Systems Samtec TSW-122-20-F-D-LL

The Header, 2.54mm, Through Hole Vertical, 44 Position (part number 02R4425) from Samtec is designed for board-to-board applications with a pitch spacing of 2.54mm. It features a two-row configuration with a total of 44 contacts. The header is constructed with a black glass-filled polyester insulator and utilizes phosphor bronze for the terminal material, which is available with either gold or tin plating over nickel. This product operates within a temperature range of -55 ¬8C to +125 ¬8C when gold plated, and -55 ¬8C to +105 ¬8C with tin plating. The voltage ratings vary depending on the mating connector, with a maximum of 550 VAC when mated with SSW connectors. The current rating per pin varies based on the mating connector type, with values ranging from 4.3 A to 6.3 A. The header is RoHS compliant and suitable for lead-free soldering in specific configurations. Engineers should consider this product for applications requiring reliable connectivity in compact spaces, particularly where high-temperature performance and compliance with environmental standards are essential.
