450V 4.5µF Capacitor
Description
A 450V 4.5µF electrolytic capacitor is a compact, polarized component designed for high-voltage precision. It stabilizes small DC rails and filters high-frequency noise. It is ideal for high-tension circuits where space is a critical constraint.
Specifications
- Capacitance: 4.5 microfarads (µF) – Precise storage for targeted filtering.
- Voltage Rating: 450 Volts (V) – Built for 240V rectified mains and high-voltage DC.
- 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; miniature cylindrical form.
Applications
- Small Power Adapters: Filters input in low-wattage AC/DC converters.
- Timing & Pulse Circuits: Used in RC networks for high-voltage timing.
- Signal Coupling: Blocks DC in high-voltage audio or sensor paths.
- LED Drivers: Provides ripple suppression in small-scale lighting drivers.
- Bypass Filtering: Shunts interference to ground in high-voltage modules.
Key Features
- Ultra-Compact: Fits into high-density power supply layouts.
- High Dielectric Strength: Resists breakdown under 450V stress.
- Low Leakage: Keeps circuits stable in sensitive analog paths.
- Rapid Response: Lower capacitance allows for fast charge/discharge cycles.
Note:
This part is polarized. Incorrect orientation leads to heating, venting, or failure. Never exceed the 450V limit. Even at low capacitance, high voltage can cause severe shock; always discharge before handling.
