A 220µF 10V electrolytic capacitor is a polarized, small-can electronic component that stores 220 microfarads of energy and handles up to 10 volts. It measures roughly 5x11mm, and works best for smoothing power in low-voltage circuits.

Capacitance: 220 microfarads (μF) to store energy.
Voltage Limit: 10 volts maximum (do not use in circuits with higher voltage).
Polarity: Positive and negative leads; putting it in backward can ruin it.
Common Uses: Power filtering, voltage smoothing, and audio signal coupling.
