470uF 450V Electrolytic Capacitor

A 470uF 450V electrolytic capacitor is a type of passive electronic component used to store and release electrical energy in circuits. Here are the key features and specifications of this capacitor:

1. Capacitance: 470 microfarads (uF)
   • The capacitance value indicates the amount of electric charge the capacitor can store. A higher capacitance value means the capacitor can store more charge.
2. Voltage Rating: 450 volts (V)
   • This is the maximum voltage that the capacitor can safely handle. Exceeding this voltage can damage the capacitor or cause it to fail.
3. Type: Electrolytic
   • Electrolytic capacitors use an electrolyte to achieve a larger capacitance per unit volume compared to other types of capacitors. They are typically polarized, meaning they have a positive and a negative terminal and must be connected correctly in a circuit.
4. Polarity: Polarized
   • These capacitors have a designated positive (anode) and negative (cathode) terminal. Incorrect polarity can lead to malfunction or damage.
5. Physical Size: Varies
   • The physical dimensions of a 470uF 450V electrolytic capacitor can vary depending on the manufacturer and the specific model. They are generally larger due to the high capacitance and voltage rating.
6. Temperature Range: Typically -40°C to +105°C
   • The operating temperature range defines the minimum and maximum temperatures at which the capacitor can operate effectively.
7. Leakage Current: Typically specified by the manufacturer
   • This is the small amount of current that flows through the capacitor even when it is not supposed to be conducting. Lower leakage current is usually preferable.
8. Equivalent Series Resistance (ESR): Important for high-frequency applications
   • ESR is a measure of the resistance that appears in series with the capacitance. Lower ESR is generally better, especially in high-frequency applications where efficiency is critical.

When selecting a 470uF 450V electrolytic capacitor, it is essential to consider factors such as the required capacitance, voltage rating, physical size, ESR, and the specific application’s thermal and electrical demands. Proper selection ensures reliable performance and longevity of the capacitor in its intended application.

Applications:

• • Used in power supply circuits for filtering and smoothing rectified DC voltages.
  • Common in audio amplifiers, motor drives, and other high-power applications.
  • Suitable for use in high-voltage circuits where large energy storage is required.
