Samtec Inc. Header, 2.54 Mm, Through Hole, 44 Contacts; Connector Systems Samtec TSW-122-08-S-D-LL

The Samtec Header, part number 02R4153, features a 2.54 mm pitch and is designed for through-hole mounting with 44 contacts arranged in 2 rows. It is compatible with various mating connectors including SSW, SSQ, SSM, and others. The header is constructed from black glass-filled polyester for the TSW variant and natural liquid crystal polymer for the HTSW variant. The terminals are made of phosphor bronze and are available with 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 for SSW and lower ratings for other types. 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 for the HTSW variant. Engineers should consider this header for applications requiring reliable board-to-board connections with specific voltage and current ratings, as well as compliance with environmental standards.
