What are the key features of EECHZ0E475?
- 4.7 F capacitance at 2.5 V in a compact 10 mm radial leaded package delivers substantial energy storage density for backup power and pulse-load applications
- Electric double-layer (EDLC) construction using activated carbon dielectric enables hundreds of thousands of charge-discharge cycles with minimal capacity degradation
- Through-hole radial leaded termination provides robust PCB mounting suitable for prototype development, energy harvesting, and industrial backup power circuits
What is EECHZ0E475 used for?
The EECHZ0E475 supercapacitor is ideal for short-term backup power, memory hold-up, and real-time clock (RTC) power supply in industrial controllers, smart meters, and consumer electronics. Its 4.7 F capacitance at 2.5 V stores sufficient energy to maintain critical circuit operation during brief power interruptions of several seconds. The long cycle life and stable EDLC chemistry also make it well suited for energy harvesting and pulse-power delivery applications.

Frequently Asked Questions
How long can EECHZ0E475 maintain power to a real-time clock circuit during a supply interruption?
With 4.7 F capacitance at 2.5 V, the EECHZ0E475 stores approximately 14.7 mJ of energy. A typical RTC circuit drawing 1 µA to 5 µA can be sustained for tens of minutes to several hours, depending on the leakage current and the minimum operating voltage threshold of the RTC device.
What makes the electric double-layer design of EECHZ0E475 suitable for high-cycle applications compared to electrolytic capacitors?
EDLC supercapacitors like the EECHZ0E475 store charge electrostatically at the activated carbon electrode surface rather than through chemical reactions, enabling cycle lifetimes exceeding 100,000 charge-discharge cycles. Standard aluminum electrolytic capacitors typically degrade after a few thousand cycles, making the EECHZ0E475 a far more durable choice for repetitive charge-discharge use cases.
What is the physical size of EECHZ0E475 and how should tolerance be considered when designing its circuit?
The EECHZ0E475 measures 10 mm in diameter with radial through-hole leads in a standard 5 mm pin spacing. Its capacitance tolerance of +40%/-20% means the actual value may range from 3.76 F to 6.58 F, so circuit designers should ensure the minimum backup duration calculation uses the lower bound of 3.76 F at 2.5 V to guarantee reliable operation.
