450V 22uF Capacitor
Description
A 450V 22µF electrolytic capacitor is a polarized component built for high-voltage filtration in space-constrained layouts. It stabilizes rectified AC power and DC-DC converters. It is designed to handle high electrical stress in demanding power circuits.
Specifications
- Capacitance: 22µF – Effective storage for ripple current smoothing.
- Voltage Rating: 450V – Rated for high-tension DC and rectified 240V mains.
- Type: Aluminum electrolytic.
- Tolerance: Typically ±20%.
- Polarity: Polarized (negative side marked with a stripe).
- Temp Range: −40°C to +85°C or +105°C.
- Package: Radial lead; slim cylindrical form.
Applications
- SMPS Primary Filter: Smooths input voltage in switching power supplies.
- LED Drivers: Provides stable DC for high-voltage lighting strings.
- Electronic Ballasts: Used in fluorescent or HID lighting control.
- Small Inverters: Manages energy transfer in low-wattage solar or UPS units.
- Industrial Controls: Filters power for high-voltage sensor modules.
Key Features
- High Voltage Resilience: Safely manages 450V DC peaks.
- Slim Profile: Fits standard high-voltage PCB layouts with tight spacing.
- Thermal Durability: Maintains performance in hot power-supply zones.
- Effective Smoothing: Reduces 50/60Hz ripple in rectification stages.
Note:
This part is polarized. Wrong installation causes internal pressure and venting. Never exceed the 450V limit. It stores a high-voltage charge; always discharge safely before handling.
