Clock/Timing - IC Batteries: Category Overview

Definition

Clock/Timing - IC Batteries are specialized power sources designed to support integrated circuits (ICs) that manage timing and clock functions in electronic systems. These batteries ensure continuous operation, data retention, and precise timing synchronization for real-time clocks (RTCs), memory backup systems, and other time-sensitive applications.

Types of Clock/Timing - IC Batteries

Lithium Coin Cells (e.g., CR2032, CR2025): Compact, long-life batteries for low-power RTCs and memory backup.
Rechargeable Lithium-Ion Batteries: For systems requiring periodic recharging and extended service life.
Supercapacitors: Offer rapid charging/discharging for high-cycle applications, bridging short power interruptions.
Thin-Film Batteries: Ultra-thin, flexible designs for space-constrained or wearable electronics.

Purchasing Recommendations

Voltage & Capacity: Match the battery s output (e.g., 3V for most RTCs) and capacity (mAh) to your IC s requirements.
Lifespan: Opt for lithium cells for long-term deployments (>5 10 years) or supercapacitors for frequent cycling.
Form Factor: Verify dimensions (e.g., coin cell diameter/thickness) for PCB compatibility.
Temperature Range: Industrial applications may need batteries rated for -40 C to +85 C.
Certifications: Prioritize UL/IEC-compliant batteries for safety-critical systems.

Ideal for embedded systems, IoT devices, and automotive electronics, these batteries are critical for maintaining accuracy during power loss. Select based on technical specs, environmental conditions, and lifecycle needs.
