Eaton Series B Supercapacitor, 1F Capacitance, 2.5V DC Voltage - B0810-2R5105-R

This supercapacitor is a cylindrical energy storage device featuring a capacitance of 1F and an operating voltage of 2.5V DC. With dimensions of 8.5mm in diameter and a height of 13.5mm, it offers a compact solution for various applications while ensuring efficient performance in energy storage.

Features & Benefits

• Low leakage current of 4μA enhances efficiency
• High-temperature tolerance from -25°C to +70°C ensures reliability
• Through-hole design simplifies integration into circuit boards
• Equivalent series resistance of 500mΩ minimises power loss

Applications

• Used for high-capacity energy storage in electronic devices
• Utilised in power backup systems
• Ideal for energy harvesting and regenerative braking systems
• Can be used with automation and electrical control systems

What are the advantages of using a cylindrical design for this component?

The cylindrical design allows for a compact footprint, which is beneficial for space-limited applications while maintaining adequate performance levels for energy storage needs.

How does the high-temperature operational range impact usability?

The wide temperature range ensures that it remains functional and reliable in diverse environmental conditions, making it suitable for various industries, including automotive and industrial controls.

What should be considered when implementing it in a circuit?

It is important to review the specified leakage current and equivalent series resistance to ensure compatibility with power requirements and to prevent performance issues in the overall circuit.

How does the electric double layer technology improve performance?

This technology allows for rapid charge and discharge cycles, making it ideal for applications where quick energy bursts are necessary, such as in energy-doubling scenarios.

What is the significance of a lifetime rating in practical applications?

A lifetime of 1000 hours indicates the expected operational length before significant degradation occurs, helping users to plan maintenance and replacements effectively to avoid system failures.
