Overview

The Panasonic FM Series 25V 220µF electrolytic capacitors are engineered for applications where low impedance and high ripple current handling are critical. With impedance ratings 40% to 70% lower than the standard Panasonic FC Series, these capacitors excel in power filtering, decoupling, and audio signal path applications. The 950 mA ripple current rating and 3000-hour endurance at 105°C make them a reliable choice for circuits that demand consistent performance under thermal stress.

Each capacitor in this six-piece set is a genuine Panasonic component (part number EEU-FM1E221), measuring 8 x 11.5mm with a 5mm lead spacing for straightforward through-hole installation. Whether you are recapping aging audio equipment, upgrading a power supply's output filtering, or building a custom circuit that demands stable, low-noise power delivery, these FM Series capacitors provide a meaningful performance improvement over general-purpose electrolytics at a compact size that fits most standard PCB footprints.
