FDK CR14250SE: Compact 1/2 AA Lithium Power for PLCs, Sensors, and Memory Backup

When space is limited but reliability can’t be compromised, the FDK CR14250SE delivers. This 3V lithium manganese dioxide cell packs steady output and low self-discharge into a compact 1/2 AA footprint (approximately 14.5×25 mm), making it ideal for PLC memory, environmental sensors, instrumentation, and security devices. In equipment that may sit idle for months yet must wake instantly, consistency matters—and the CR14250SE is engineered for precisely that duty.

Why Designers Choose CR14250SE

• Small size, serious endurance: The 1/2 AA format fits tight boards and enclosures while offering multi-year service in low-drain applications.
• Low self-discharge: Keep spares ready for long maintenance intervals; deploy confidently in remote assets.
• Stable 3V output: Clean, predictable voltage simplifies regulator selection and firmware thresholds.
• Mechanical flexibility: Available bare or with solder tabs for positive retention in industrial environments.

Typical Applications

The FDK CR14250SE shines in memory backup for PLCs and controllers, real-time clocks, access control panels, and compact sensors. It’s also a favorite in handheld meters and medical accessories where board space is tight yet uptime is critical. Because it tolerates long standby and periodic wake cycles, it’s well-suited for devices that transmit in bursts or log data intermittently.

Integration Tips

1. Define your current profile: Measure sleep, wake, and peak transmit currents. This clarifies expected life.
2. Add local capacitance: For burst loads, a low-ESR capacitor can deliver spikes while the battery supplies steady draw.
3. Mind your thresholds: Set firmware cutoffs that preserve reserve and avoid deep discharge.
4. Choose tabs when needed: For vibration or high-duty installations, tabbed cells enhance reliability.

Field Reliability Practices

Store cells within recommended temperatures and avoid prolonged exposure to heat. Clean contacts, verify polarity, and secure cells to prevent movement. In service logs, track installation dates and device load estimates; this helps maintenance teams plan proactive replacements before critical events.

FAQ

Is CR14250SE rechargeable? No. It’s a primary lithium manganese dioxide cell meant for single-use, long-duration applications.

Can it handle pulses? For short spikes, pair the battery with appropriate capacitors and design for average current within recommended limits.

What about shelf life? CR chemistry is known for excellent shelf readiness; with proper storage, cells remain serviceable for years.

Bottom Line

FDK’s CR14250SE gives engineers a compact, predictable power source for space-constrained designs. It’s the right fit when you need years of dependable 3V output in a 1/2 AA form factor. Check out these fine offerings.
