The Samtec TSW-121-16-G-T-RA is a versatile strip post header designed for through-hole mounting. It utilizes a .100" (2.54mm) pitch and is constructed with a phosphor bronze body and plated with gold and tin for optimal conductivity and corrosion resistance. The insulator material is typically black glass filled polyester or natural liquid crystal polymer, depending on the specific series. This connector is ideal for applications requiring a secure and reliable connection, commonly found in industrial automation, telecommunications, and consumer electronics. It is RoHS compliant and lead-free solderable, ensuring environmental responsibility and ease of integration into modern manufacturing processes.
