The SND Series is currently available,
although not recommended for new
designs.
Features
■ Double contacts offer high reliability
■ Low contact resistance
■ Self-clean on contact area
■ Splay terminals allow for automatic
insertion by IC insertion machine
■ Straight terminals are available for
manual insertion
■ RoHS compliant*
