Overview

The Panasonic FM Series 25V 680uF Capacitors are high-performance electrolytic capacitors engineered for applications where low ESR and low impedance are critical. With a capacitance of 680 microfarads and a voltage rating of 25V, they are commonly used in power supply output filtering, voltage regulation stages, and audio circuits where stable, clean power delivery directly impacts performance. The FM Series is one of Panasonic's most respected capacitor lines, recognized for tight manufacturing tolerances and consistent electrical characteristics across units.

Rated for continuous operation at temperatures up to 105°C, these capacitors are built to perform reliably even in enclosures with limited airflow or alongside heat-generating components. The low ESR characteristic minimizes resistive losses within the capacitor itself, which translates to better ripple current handling and less self-heating during operation. Sold as a set of 6, this package provides a practical quantity for common motherboard capacitor replacements, power supply rebuilds, or custom electronics projects that call for proven, high-quality passive components.

Pros & Cons

👍 Pros

  • Low ESR design reduces energy loss and heat buildup during operation.
  • 105°C temperature rating supports use in higher-heat environments and demanding circuits.
  • Panasonic FM Series is a well-regarded line known for consistent quality and longevity.
  • Six-piece quantity provides enough units for common repair or upgrade projects.
  • 680uF at 25V is a widely used rating for power supply filtering and decoupling applications.

👎 Cons

  • Only available in a single capacitance and voltage rating, requiring separate purchases for other values.
  • Six units may not be enough for larger-scale board repairs or projects requiring many replacements.
  • As electrolytic capacitors, they have a finite lifespan and will eventually need replacement after years of service.
  • No datasheet or pinout reference is included in the package for less experienced builders.

Frequently Asked Questions

This set includes 6 Panasonic FM Series capacitors.
Low ESR (Equivalent Series Resistance) means these capacitors produce less internal heat and waste less energy, resulting in more efficient and stable performance in electronic circuits.
They are rated for operation up to 105°C, which makes them suitable for use in environments where components may generate significant heat.
They are popular choices for power supply filtering, motherboard and graphics card repairs, audio equipment, and other electronic circuits that benefit from stable, low-impedance capacitance.
Yes, as electrolytic capacitors they are polarized and must be installed with correct orientation in the circuit.
