FDK CR17450SE: 3V Lithium Cylinder for Meters, Instruments, and Backup Power

The FDK CR17450SE provides a smart balance of size and endurance for devices that outgrow shorter cells. With a cylindrical 17×45 mm format and 3V nominal output, it’s a natural match for metering, alarms, data recording, tracking devices, and control systems that require multi-year standby with intermittent wake cycles. Low self-discharge and consistent voltage delivery help ensure your product behaves the same on day 1,000 as it did on day one.

Why the 17450 Size?

Designers often face a trade-off between footprint and runtime. The 17450 size slides into enclosures that cannot accept full “A” length cells but still need materially more capacity than a stubby format. That extra length buys longer maintenance intervals, better headroom for bursts, and a margin of safety as devices age and current draw subtly shifts.

Key Advantages

• Steady voltage: A flat discharge profile supports stable electronics and predictable firmware behavior.
• Low self-discharge: Ideal for equipment that spends most time asleep, waking for scheduled tasks.
• Mechanical options: Bare or tabbed versions allow secure mounting and clean harness design.
• Wide service window: Designed for dependable performance across varied ambient conditions.

Best-Fit Applications

Utility meters and sub-metering hardware, process instrumentation, access control, environmental monitoring, and alarm systems all benefit from the CR17450SE’s blend of compact size and staying power. Its predictable curve simplifies regulator and threshold settings; operations teams can forecast service windows with confidence.

Design & Deployment Guidance

1. Profile your load: Quantify sleep vs. wake currents; match to expected service life goals.
2. Plan for pulses: Add bypass capacitors near RF stages or MCU rails to handle burst demands gracefully.
3. Secure installation: Use tabbed cells where vibration or orientation could loosen spring contacts.
4. Temperature awareness: Place cells away from heat sources; document ambient ranges during pilot deployments.

Maintenance & Safety

Follow polarity marks, avoid short circuits, and never attempt to recharge primary lithium cells. For fleet deployments, barcode labels and install-date logs streamline preventive maintenance and traceability. Store spares in original packaging and rotate stock on an annual schedule.

Bottom Line

The FDK CR17450SE is a right-sized 3V cylinder that extends runtime without consuming a full-size footprint. If your device needs years of dependable service with occasional bursts of activity, this cell is a strong match. Check out these fine offerings.
