SURFACE MOUNT (SMT) & THRU HOLE (THM) BUTTON CELL RETAINERS
Economical and reliable SMT and THM coin cell retainers specifically designed for miniature electronic applications with limited board space.
• THM legs maintain relative position during and after soldering • Ideally suited for High Density packaging • Reliable spring tension assures low contact resistance
• Available in Thru Hole Mount (THM) or Surface Mount (SMT) configurations • Retains battery securely to withstand shock and vibration
• SMT solder tail with “flow-hole” design for increased joint strength • Solder tail located outside of retainer body which facilitates visual inspection of the solder joints
