250V 4.7uF Capacitor
Description
A 250V 4.7µF electrolytic capacitor is a polarized component used for high-voltage signal decoupling and small-scale filtering. It provides precise voltage stabilization in compact high-voltage circuits. It is ideal for applications where space is limited but voltage demands are high.
Specifications
- Capacitance: 4.7 microfarads (µF) – Optimized for precision filtering.
- Voltage Rating: 250 Volts (V) – High dielectric strength for rectified DC 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; miniature cylindrical form.
Applications
- Small Power Supplies: Filters noise in low-wattage AC/DC converters.
- Ignition Circuits: Used in electronic triggers and small pulse generators.
- Signal Coupling: Blocks DC while passing AC in high-voltage audio paths.
- Bypass Filtering: Shunts high-frequency interference to ground.
- Timing Circuits: Supports RC networks in high-voltage timing delay units.
Key Features
- Miniature Size: Fits into high-density, space-constrained PCBs.
- Low Leakage: Maintains charge stability in sensitive analog circuits.
- Fast Charging: Lower capacitance allows for rapid response cycles.
- High-Voltage Safety: Built to withstand 250V in a small footprint.
Note:
This part is polarized. Incorrect installation causes internal heating or failure. Never exceed the 250V limit. Despite its small size, it can store high voltage; handle with caution during testing.
