Coin/Button Cell - Retainers & Contacts

PCB Lithium Coin Cell Battery Retainers

(THM) Thru Hole Mount & (SMT) Surface Mount Available for 4.8mm, 5.8mm, 6.8mm, 7.9mm, 9mm, 10mm, 11.6mm, 12mm, 16mm, 20mm, 23mm and 24mm Dia. Cells

Designed for memory back-up and stand-by applications,  these contacts permit quick and easy coin cell replacement and installation. Eliminating "soldered-in" cells, computer, video, telecommunication and similar PCB based product users now have a reliable, "no tools required" method for changing batteries.

Extremely economical, these retainer contacts are available in surface mount (SMT) or thru hole mount (THM) styles for 4.8mm, 6.8mm, 11.6mm,12mm, 16mm, 20mm, 23mm and 24mm coin cells. The THM version has stable mounting legs for excellent board retention during wave solder. The SMT version includes a unique solder tail "flow-hole" design to bolster reflow and strengthen solder joints. They are manufactured from phosphor bronze, precision stamped and are plated with either a high luster nickel finish or matte tin finish ideal for low temperature soldering enviornments. Both feature dual spring contacts to assure reliable connections and a low contact resistance.

Balanced and light weight for pick up and placement, these contacts are compatible with vacuum and mechanical assembly systems. The SMT version is available on tape and reel and the carrier tape is conductive polystyrene which meets the ANSI/EIA - 481 standard. Also Available are Optional Negative Bottom Contacts in both Thru Hole and Surface Mount Styles:
