250V 220uF Capacitor
Description
A 250V 220µF electrolytic capacitor is a high-capacity polarized component. It is designed for efficient power smoothing and energy storage. It effectively handles high-voltage ripples in large power supplies.
Specifications
- Capacitance: 220µF – High capacity for substantial energy reservoirs.
- Voltage Rating: 250V – Optimized for rectified mains and DC bus lines.
- 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 or snap-in; cylindrical form factor.
Applications
- Switching Power Supplies: Smooths output in high-wattage adapters.
- Audio Amplifiers: Provides bulk energy storage for power stages.
- Motor Starters: Assists in initial current delivery for small motors.
- Rectifier Circuits: Reduces voltage ripple in AC-to-DC conversion.
- Desktop PCs: Used in the primary stage of ATX power units.
Key Features
- High Capacitance: Stores significant charge to prevent voltage drops.
- Low ESR: Minimizes internal heat during high-current demands.
- Ripple Current Handling: Manages heavy electrical noise effectively.
- Broad Compatibility: Fits various consumer and industrial PCB designs.
Note:
This part is polarized. Reversed installation causes internal pressure and failure. Never exceed the 250V limit. High-capacity capacitors store lethal charge; discharge safely before touching.
