Overview
The Keystone 247 is a surface-mount battery clip designed to secure 20mm to 21mm cylindrical batteries, such as CR2032 or similar lithium coin cells. Manufactured from spring steel with a tin-nickel plating, it provides a low-profile and reliable electrical connection directly to the PCB. Its compact 14.5mm by 21mm footprint makes it ideal for space-constrained electronics that require user-replaceable power sources.
Why Choose This Part
The spring steel construction ensures high retention force and durability over multiple battery cycles. The tin-nickel plating offers excellent solderability and resistance to corrosion, while the surface-mount design simplifies automated assembly and reduces PCB height compared to through-hole holders.
Applications
Real-Time Clock (RTC) Backup
Providing reliable power to maintain system time in industrial controllers and motherboards during main power loss.
Memory Retention
Securing backup batteries for SRAM or volatile configuration registers in embedded systems.
Compact IoT Sensors
Serving as the primary power contact for low-power wireless nodes and environmental sensors.
Handheld Medical Devices
Integrating into portable diagnostic tools that require a secure, vibration-resistant battery connection.
