Samtec Inc. Header, 2.54 Mm, Through Hole, 50 Contacts; Connector Systems Samtec TSW-150-09-S-S-RA

The Header, 2.54 mm, Through Hole, 50 Contacts (part number 03R3479) from Samtec is designed for board-to-board applications with a pitch spacing of 2.54 mm. It features a single row configuration with 50 contacts and is compatible with various mating connectors including SSW, SSQ, SSM, and others. The header is constructed with a black glass-filled polyester insulator and utilizes phosphor bronze for the terminals, which can be plated with either gold or tin 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, reaching up to 550 VAC 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 solderable options. Engineers should consider this product for applications requiring reliable connections in compact spaces, particularly where high-temperature performance and compliance with environmental regulations are critical.
