HW-20-08-T-S-310-SM Description

Short technical summary and product information.

The Samtec HW-20-08-T-S-310-SM is a high-temperature flexible board stacking header designed for surface-mount applications. It features 20 positions in a single row with a 2.54mm (0.100") pitch, making it suitable for standard board-to-board spacing requirements. The header uses tin-plated phosphor bronze contacts and a black LCP (Liquid Crystal Polymer) insulator, offering reliable performance in elevated temperature environments.

Key specifications include an operating temperature range of -55°C to +105°C when using the tin contact finish, and a maximum SMT lead coplanarity of 0.15mm. The surface-mount solder termination ensures compatibility with standard SMT assembly processes. This component is part of Samtec's Flex Stack design family, which allows for customized stacker heights through the part number suffix.

Designed for elevated board stacking in high-temperature processing environments, this header provides a reliable interconnection solution for PCB assemblies requiring precise alignment and robust electrical contact. The single-row configuration simplifies routing and saves board space in dense designs.
