Samtec Inc. Header, 2.54 Mm, Through Hole, 39 Contacts; Connector Systems Samtec TSW-113-20-S-T

The Header, 2.54 mm, Through Hole, 39 Contacts (part number 71X0938) from Samtec is designed for board-to-board applications with a pitch spacing of 2.54 mm. It features three rows and a total of 39 contacts, making it suitable for various electronic connections. The header is constructed with a black glass-filled polyester insulator and utilizes phosphor bronze for the terminals, which are 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, with values ranging from 4.3 A to 6.3 A. The header is RoHS compliant and offers lead-free solderability for specific versions. Engineers should consider this product for applications requiring reliable connections in a compact form factor, particularly in environments where temperature and voltage ratings are critical.
