Designed for memory backup and standby applications, Keystone Electronics Corporation's compact battery contacts permit quick and easy coin cell replacement and installation. By eliminating "soldered-in" cells, computer, video, telecommunication and similar PCB based product users now have a reliable, "no tools required" method for changing batteries.
These retainer contacts are available in surface mount (SMT) or through-hole mount (THM) styles for 4.8mm-24mm coin cells. The THM version has stable mounting legs for excellent board retention during wave soldering. The SMT version includes a unique solder tail "flow-hole" design to bolster reflow and strengthen solder joints. Both feature dual spring contacts to assure reliable connections and a low contact resistance.
