WE-SECF SMD EMI Contact Finger

WE-SECF SMD EMI Contact Finger

Wurth Electronics' WE-SECF series of contact fingers are made of gold-plated copper-beryllium, in contrast to competitor products. The copper-beryllium material prevents the parts from corroding and provides very low resistance. With their wide gold-plated surface, they discharge high frequency interferences to contacted housings or mass layers of adjacent PCBs at lower impedances. Embedded systems of all kinds can thus be installed touching each other or conductive housings cost-efficiently in the smallest spaces. This saves assembly effort and costs in production. High temperatures and mechanical weight have no influence on the excellent connection properties on the EMI contact finger.
