250V 22uF Capacitor
Description
A 250V 22µF electrolytic capacitor is a polarized component designed for high-voltage filtering in compact electronics. It balances energy storage with a small physical size. It is ideal for stabilizing DC rails in mid-range power applications.
Specifications
- Capacitance: 22 microfarads (µF) – Efficient storage for ripple suppression.
- Voltage Rating: 250 Volts (V) – Safe for rectified 110V/120V mains and DC buses.
- Type: Aluminum electrolytic.
- Tolerance: Typically ±20%.
- Polarity: Polarized (negative lead marked by a stripe).
- Temp Range: −40°C to +85°C or +105°C.
- Package: Radial lead; slim cylindrical form.
Applications
- LED Drivers: Filters output to provide steady, flicker-free lighting.
- Power Adapters: Smooths DC voltage in medium-power chargers.
- Audio Amps: Filters power noise in pre-amp and driver stages.
- Energy Harvesting: Stores charge in small-scale high-voltage sensors.
- Household Appliances: Used in control boards for small motors or timers.
Key Features
- Compact High-Voltage Storage: High capacity-to-volume ratio.
- Low Impedance: Effectively reduces high-frequency ripples.
- Steady Performance: Maintains capacitance over its rated life.
- Versatile Fit: Ideal for height-restricted PCB enclosures.
Note:
This part is polarized. Installing it backwards leads to gas buildup and venting. Never exceed the 250V limit. Discharge before touching, as 22µF at high voltage can hold a significant electrical charge.
