Nichicon Aluminium Electrolytic Capacitor: A Reliable Choice for Electronic Applications


Nichicon is a well-established Japanese company that specializes in the design and manufacture of high-quality aluminium electrolytic capacitors. These capacitors are widely used in various electronic applications, including power supplies, audio equipment, and industrial control systems. In this article, we will delve into the features, benefits, and applications of Nichicon aluminium electrolytic capacitors.

Construction and Characteristics

Nichicon aluminium electrolytic capacitors consist of an aluminium foil anode and a cathode made of manganese dioxide or conductive polymer. The electrolyte is a solution of boric acid and ammonium borate, which helps to reduce the equivalent series resistance (ESR) and improve the overall performance of the capacitor.

The capacitors have a compact, cylindrical design with a radial lead configuration, making them suitable for surface-mount and through-hole applications. They are available in a range of capacitance values, from 1 μF to 100,000 μF, with voltage ratings up to 500 VDC.

Features and Benefits

Nichicon aluminium electrolytic capacitors offer several benefits that make them a popular choice among electronics engineers and designers:

  • Low Equivalent Series Resistance (ESR): Nichicon capacitors have a low ESR, which helps to reduce power losses and improve the overall efficiency of the circuit.
  • High Ripple Current Capability: These capacitors can handle high ripple currents, making them suitable for use in switching power supplies and other high-frequency applications.
  • Long-Life and Reliability: Nichicon capacitors have a long lifespan, with a minimum of 2,000 hours at 105°C, ensuring reliable performance over an extended period.
  • Compact Size: The compact design of these capacitors makes them ideal for use in space-constrained applications.


Nichicon aluminium electrolytic capacitors are suitable for a wide range of applications, including:

  • Power Supplies: These capacitors are used in switching power supplies, DC-DC converters, and AC-DC power supplies.
  • Audio Equipment: They are used in audio amplifiers, speakers, and other audio equipment to filter and regulate voltage levels.
  • Industrial Control Systems: Nichicon capacitors are used in industrial control systems, such as motor control units, programmable logic controllers (PLCs), and robotics.
  • Automotive Systems: They are used in automotive systems, such as engine control units, anti-lock braking systems (ABS), and electronic stability control (ESC) systems.


Nichicon aluminium electrolytic capacitors are a reliable choice for electronic applications that require high performance, compact design, and long lifespan. With their low ESR, high ripple current capability, and long-life characteristics, these capacitors are suitable for use in a wide range of applications, from power supplies to industrial control systems.
