Overview
The Keystone 3002 is a surface-mount battery retainer designed to secure 20mm coin cells, such as the CR2032, directly to a printed circuit board. It features a low-profile phosphor bronze design with nickel plating to ensure reliable electrical contact and mechanical stability. This retainer is ideal for compact electronic assemblies where a traditional battery holder would occupy too much vertical space.
Why Choose This Part
The SMT design allows for automated pick-and-place assembly, significantly reducing manufacturing costs compared to through-hole alternatives. Its open-top construction permits easy battery replacement without specialized tools, while the phosphor bronze material maintains consistent spring tension over the life of the product.
Applications
Real-Time Clock (RTC) Backup
Providing reliable power to RTC circuits in industrial controllers and consumer electronics during primary power loss.
Wireless Sensor Nodes
Securing 20mm lithium cells in IoT devices and remote sensors that require a small footprint.
Handheld Medical Devices
Integrated into portable diagnostic tools where height constraints are critical and SMT assembly is required.
