When circuit board height is a critical design parameter, Keystone offers a solution with an ultra-low profile holder for the #2032 Lithium Coin Cells. These new holders rise 2 mm above the PCB surface and are ideal for retaining cells securely under shock and vibration in high-density applications for PCB requirements.
The reduction in the height of the holder on a circuit board is achieved by the method of partially mounting the holder thru a hole in the PCB, allowing the holder to sit through the PCB. Built In Stabilization tabs in the LCP, UL 94V-0 base add mounting security while Gold plated contacts assure increased PCB and solder joint mounting strength.
These polarized coin cell holders are supplied on tape and reel (Part #1057TR) and in bulk (Part #1057) and feature dual-spring contacts. Importantly, the holders may be used with most vacuum and mechanical pick-and-place assembly systems.
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 a comprehensive 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.
