## Summary description

Electrochemical supercapacitor EB1299902409 with 30 farad capacitance and 2.8 V DC rated voltage, cylindrical Ø12.5×34 mm. Designed for short-term energy storage, backup power, pulse power delivery and smoothing supply fluctuations in electronic circuits. Compact size suits embedded systems, RTC backup and energy-harvesting applications.

## Long description

Electrochemical supercapacitor EB1299902409 with 30 F capacitance and 2.8 V DC rated voltage is a compact cylindrical energy storage component with dimensions Ø12.5×34 mm. It is intended for short-term energy storage, backup power for real-time clocks and volatile memory, pulse current delivery and smoothing of supply fluctuations in electronic circuits. The small diameter and low profile make it suitable for space-constrained designs where quick charge/discharge cycles and high cycle life are required.
Advantages
The supercapacitor offers high capacitance in a compact package, enabling rapid charge and discharge with low internal resistance. Its rated voltage of 2.8 V and 30 F capacitance provide significant energy density for short-duration applications compared with conventional capacitors. The component is designed for long cycle life and stable performance over many charge/discharge cycles, making it a reliable choice for frequent backup and pulse-power applications. Its cylindrical form factor simplifies PCB layout and keeps mechanical integration straightforward.
Suitable for
 RTC and CMOS memory backup in embedded systems
 Power smoothing and decoupling in supply rails
 Pulsed power delivery for sensors, transmitters and actuators
 Energy harvesting storage for short-term buffering
 Prototyping and compact electronic modules with limited board space
Key specifications
 Capacitance: 30 farads
 Rated voltage: 2.8 V DC
 Package shape: cylindrical
 Dimensions: diameter 12.5 mm, length 34 mm
 Typical applications: short-term energy storage, backup power, pulse current delivery
 Charge/discharge characteristic: rapid charge/discharge suitable for high current pulses
How to use
Install the supercapacitor on the PCB according to the device polarity and recommended clearance for its cylindrical body. Observe correct polarity during soldering or through-hole mounting and follow the PCB manufacturer's guidelines for heating profiles. Charge and discharge the component within its rated voltage (maximum 2.8 V) and design the circuit to limit inrush currents if required. For backup applications, connect the supercapacitor through a current-limiting resistor or charging circuit that prevents overvoltage. Include proper balancing or protection when using multiple capacitors in series.
Usage recommendations
Store and operate the supercapacitor within the temperature and humidity ranges specified by the system design. Avoid exceeding the rated voltage and ensure adequate current limiting during charging to maximize cycle life. For long-term backup, verify self-discharge characteristics in your application and consider periodic maintenance checks. When integrating into safety-critical circuits, add appropriate supervision and protective elements to prevent damage from overvoltage or reverse polarity.
