Samtec Inc. Header, 5.08Mm, Though Hole Vertical, 4 Position; Connector Systems Samtec TSW-204-14-T-S-LL

The Samtec Header, part number 03R5990, is a through-hole vertical connector with a pitch spacing of 5.08 mm and four positions. It is designed for board-to-board applications and features a single row configuration. 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 connector 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 product is RoHS compliant and lead-free solderable for specific versions. Engineers should consider this header for applications requiring reliable electrical connections in compact spaces, particularly where high-temperature performance is necessary.
