Low-profile lithium coin cell holders

10 June 2009 Interconnection

Keystone Electronics has designed new low-profile holders for the secure retention of #2450 lithium coin cells. These new holders are rugged and will retain cells securely under shock and vibration in high-density applications for PCB requirements.

These polarised coin cell holders feature dual-spring contacts and are supplied on tape and reel and in bulk formats; they may also be used with most vacuum and mechanical pick-and-place assemblies. Manufacture is with 0,20 mm thick phosphor bronze, gold plate over a glass-filled LCP base, rated UL 94V-0. Polystyrene carriers, meeting ANSI/EIA-481 standards, are utilised for tape and reel parts with 13 inch reels to hold 450 parts on 24 mm pitch, 44 mm wide tapes.

The company’s full line of battery hardware also consists of SMT and THM products including contacts, clips, holders, retainers and straps in assorted materials for coin cells and batteries. In addition to its line of interconnect hardware and components, Keystone provides application engineering services for product modification and special design requirements, supported by pro-active stamping, machining and assembly operations.
