Aluminum Electrolytic Capacitor - Radial 50V
Description / Aluminum Electrolytic Capacitor - Radial 50V
Radial aluminum electrolytic capacitors rated 50V, available from 1.0µF to 1000µF. Polarized — connect the positive leg (longer lead, or the leg opposite the stripe) to the positive rail in your circuit.

Common uses:
- AC→DC smoothing: A 100µF electrolytic wired in parallel with an animated LED smooths the pulsed DC from a bridge rectifier, giving the built-in IC a stable supply voltage. Required when powering animated LEDs from 12V AC landscape transformers or DCC model railroad track power — see the full wiring guide.
- 555 timer oscillators: The RC timing network controls blink or flash rate. Values from 10µF–470µF cover slow blink rates (0.5–5 Hz) at typical resistor values. See our 555 timer LED blinker guide for a complete circuit with component value tables.
- Power supply filtering: Smooth rectified DC after a bridge rectifier. Larger values (220µF–1000µF) are common in bulk filter stages. See the power supply filter capacitor guide for how ripple reduction works and how to size the capacitor.
- Decoupling: Lower values (1µF–10µF) decouple analog and audio supply rails; pair with a 100nF ceramic capacitor for broad-spectrum noise rejection. See our decoupling capacitor guide for placement rules and value selection.
