The EECF5R5U474 is an electric double-layer capacitor (EDLC), also known as a supercapacitor or ultracapacitor, manufactured by Panasonic. These capacitors are energy storage devices that bridge the gap between conventional capacitors and batteries, offering high capacitance values and fast charge/discharge rates.

Applications:

• Memory backup in electronic devices (e.g., RTC - Real Time Clock).
• Energy harvesting applications for storing energy generated from ambient sources.
• Power assist in battery-powered devices to provide peak current support.
• Energy storage in low-power devices.
• Pulse power applications.

Features:

• High capacitance value of 0.47F (Farads).
• Voltage rating of 5.5VDC.
• Low equivalent series resistance (ESR) for efficient energy transfer.
• Long cycle life, capable of withstanding hundreds of thousands of charge/discharge cycles.
• RoHS compliant.

Benefits:

• Long-term memory backup without the need for battery replacement.
• Fast charging and discharging capabilities for quick energy delivery.
• High energy density compared to conventional capacitors.
• Environmentally friendly due to the absence of hazardous materials.
• Reduced maintenance costs due to long cycle life.

Additional Details:

The EECF5R5U474 supercapacitor utilizes an electrochemical double layer to store energy. This double layer is formed at the interface between an electrode and an electrolyte. The capacitance value is determined by the surface area of the electrode and the distance between the electrodes. Supercapacitors have a much higher energy density than conventional capacitors because they can store more charge for a given size.

The low ESR of the EECF5R5U474 allows for efficient energy transfer, minimizing energy loss during charging and discharging. The long cycle life makes it suitable for applications that require frequent charge/discharge cycles. The 5.5V voltage rating makes it compatible with many low-voltage electronic circuits. This supercapacitor is commonly used in applications where a small amount of energy needs to be stored for a short period of time, such as memory backup or power assist. Its rapid charge/discharge characteristics are beneficial for handling burst power demands.
