68uF 25V Radial Electrolytic Capacitor

68uF 25V Radial Electrolytic Capacitor

The 68uF 25V radial electrolytic capacitor is a compact, aluminum-based passive component designed for energy storage, voltage smoothing, and noise filtering in low-voltage DC circuits. With a rated capacitance of 68 microfarads and a voltage tolerance up to 25 volts, this radial electrolytic capacitor offers dependable performance in space-limited PCB layouts. It is commonly used in switch-mode power supplies (SMPS), embedded microcontroller boards, USB power regulation, audio equipment, and LED lighting systems.

Popular series such as the Panasonic FR and HD models feature long service life (up to 5,000 hours at 105 °C), low ESR (typically around 300 milliohms), and ripple current ratings of 240 to 280 mA. SMD versions, like Panasonic FK or Nichicon polymer alternatives, are available in sizes ranging from 6.3 mm × 5.8 mm to 11 mm in length, making the 68uF 25V radial electrolytic capacitor an excellent choice for modern compact circuit designs.

Manufacturers such as Panasonic, KEMET, Nichicon, Rubycon, and Wurth offer high-reliability variants of the 68uF 25V radial electrolytic capacitor, optimized for thermal stability and consistent operation in high-frequency environments. The component is RoHS-compliant and suitable for consumer electronics, DC-DC converters, lighting drivers, and industrial control applications.
