PL IA NT Features CO M ■ Simple installation *R oH S ■ Enables board mounted, replaceable 5-pin protection ■ Industry standard footprint ■ Gold plated contact points ■ RoHS compliant* 85028 Receptacle for 5-Pin Surge Protectors Bourns® 85028 receptacles are a convenient way to add primary surge protectors to printed circuit boards. They accept Bourns® 24xx Series 5-Pin Surge Protectors and other manufacturers’ 5-pin protectors. These adapters are equipped with gold-plated contacts for excellent conductivity and corrosion resistance. The 85028-2 has short mounting pins for PCB through-hole mounting and the 85028-1 has extended pins for wire-wrap applications. The 85028-3 has four short pins and one long pin for the ground connection. The block is made from telecom-grade, V94-0 UL rated thermoplastic.
