Harwin S8411-45R Surface Mount Battery Holder for CR1220 Coin Cell (SMD / SMT)

Provide reliable backup power to your real-time clocks (RTC) and non-volatile memory chips with the S8411-45R surface-mount coin cell battery holder from Harwin. Specifically designed for standard CR1220 (12mm diameter) 3V lithium coin cells, this ultra-compact metal retainer clip delivers a secure, low-profile mechanical grip on the battery while maintaining minimal PCB footprint.

Constructed from gold-plated tin-bronze / phosphor bronze materials, the S8411-45R ensures ultra-low contact resistance and high corrosion resistance over long deployment lifetimes. Its tape-and-reel compatible SMT design enables fast automated pick-and-place assembly, making it an essential component for compact IoT sensors, smart metering systems, medical devices, automotive RTC modules, and custom handheld electronics.

Key Features:

• Designed for CR1220 Batteries: Perfectly fits standard 12mm diameter lithium coin cells (CR1220 / BR1220).

• Ultra-Low Profile SMD Design: Minimizes total vertical height above the board surface for super-slim enclosures.

• Gold / Tin Contact Plating: Ensures superior electrical conductivity, low contact resistance, and prevention of surface oxidation.

• Automated Assembly Ready: Surface-mount terminals engineered for standard SMT reflow soldering and automated pick-and-place equipment.
