Gold plated contacts for increased electrical conductivity. Furthermore, the gold plated contacts provide greater resistance to corrosion compared to nickel plated contacts.
The clip for the SMTU-C holders is positioned on the positive contact to improve the vibration and shock sustainability of the coin cell when axial forces impact the application. The clip fixes itself on the top of the coin cell to provide this protection. There are no dimensional changes for mounting the holder in an application; meaning, customers can use these new holders without changing the layout of the PCB.
Additional positioning pins enable easy and safe PCB mounting
