Power Cuts Wipe Data: DKT-DA Super Capacitor Protects RAM, RTC & Smart Meters

Kingtronics International Company —Inspired by Innovation

Dear Designers and Engineers,

In the world of smart devices and embedded systems, even a millisecond of power loss can result in irreversible damage — lost memory, corrupted data, or desynchronized real-time clocks (RTC). Whether you’re designing smart meters, SRAM modules, or embedded control boards, your system’s stability depends on how well it handles brief but critical power interruptions.

That’s why design engineers choose the Kingtronics DKT-DA Series — a 5.5V coin-type super capacitor that delivers fast, compact, and reliable backup exactly when you need it.

Why It Matters

• RAM loses data instantly during sudden voltage drops if not protected

• RTC modules can reset, throwing off timestamps in metering or logging systems

• Traditional capacitors may not respond fast enough

• Batteries degrade over time and require maintenance

The DKT-DA is engineered to close this gap — giving your circuits the precious milliseconds needed to retain memory, store data, or shut down properly.

Designed for Embedded & Industrial Use

The DKT-DA Series is compact and lightweight, making it ideal for designs with limited PCB space. It’s a go-to solution for:

• Smart meters (anti-power loss for RTC & logging)

• RAM/RTC modules (volatile data retention)

• Compact UPS systems

• Automotive electronics

• Consumer and IoT devices

Its wide capacitance range and flexible mounting options (C/V/H) let you integrate power protection into any design without reworking your layout.
