Plastic Shell Capacitor (Plastic Round Capacitor) — Description:

A Plastic Shell Capacitor is an electrical component designed to store and release electrical energy in a circuit. These capacitors are encased in a durable plastic shell, providing excellent insulation, mechanical protection, and moisture resistance. The plastic enclosure also makes them lightweight and corrosion-resistant, suitable for a wide range of indoor and outdoor applications.

Key Features:

• Encapsulated in a non-conductive plastic shell for enhanced durability.

• Stable capacitance and low leakage current.

• Excellent resistance to moisture and environmental factors.

• Compact, lightweight, and easy to mount.

• Commonly used for AC motor starting, power factor correction, filtering, and energy storage.

Applications:

• Air conditioners and refrigerators.

• Ceiling fans and pumps.

• Power supplies and inverters.

• Industrial machinery.

• Lighting systems.

Typical Specifications:

• Capacitance Range: 1 µF – 100 µF (varies by model)

• Voltage Rating: 250V ~ 450V AC

• Tolerance: ±5% or ±10%

• Operating Temperature: -25°C to +70°C

• Plastic round capacitors, also known as plastic shell capacitors, are a type of capacitor widely used in electronic circuits for various applications. They offer several advantages and come in different capacitance values (measured in microfarads, or μF). Here are some common capacitance values and their typical uses:
  1. 0.1 μF to 1 μF: Capacitors in this range are commonly used for decoupling and bypassing applications. They help filter out high-frequency noise and stabilize voltage levels in electronic circuits, especially in power supply sections.
  2. 1 μF to 10 μF: These capacitance values are often used in coupling and audio frequency applications. They can be found in audio amplifiers, preamplifiers, and other audio-related circuits where signal coupling or blocking is required.
  3. 10 μF to 100 μF: Capacitors in this range are suitable for filtering low-frequency signals, such as in power supply filters or audio crossover networks. They help smooth out voltage ripples and provide stable DC voltage outputs.
  4. 100 μF to 1000 μF: These higher capacitance values are commonly used for bulk energy storage, especially in power supply circuits and other applications requiring larger capacitance. They help store and release electrical energy as needed.
  5. Above 1000 μF: Capacitors with capacitance values above 1000 μF are typically used for applications that require large energy storage or smoothing capacitors in high-power systems, such as power amplifiers or industrial equipment.
