Product type
Paper capacitors are passive electronic components that store electrical energy in an electric field. They are constructed using a thin layer of paper impregnated with a dielectric material, which enhances their capacitance. This type of capacitor is known for its reliability and stability over time, making it suitable for various applications in electronic circuits.
| Capacitance range | 1 nF to 10 µF |
| Voltage rating | 50 V to 1000 V |
| Dielectric material | Paper impregnated with oil or resin |
| Temperature range | -40°C to +85°C |
| Tolerance | ±5% to ±20% |
When selecting a paper capacitor, consider the required capacitance value and voltage rating for your application. It's also important to specify the temperature range and tolerance that fits your circuit design. Additionally, inquire about any specific certifications or standards that may be necessary for your industry, and determine the quantity needed for your project to receive an accurate quote.

Paper capacitors offer excellent stability, low leakage current, and good performance in audio applications.
While they can be used in some high-frequency applications, their performance may not be as optimal as other capacitor types like ceramic or film capacitors.
Paper capacitors typically have a long lifespan, often exceeding 10 years, depending on operating conditions.
No, paper capacitors are non-polarized, allowing them to be connected in either direction in a circuit.
The right capacitance value depends on the specific requirements of your circuit, including frequency and load characteristics.
Paper capacitors can contain oil or resin, so proper disposal methods should be followed to minimize environmental impact.
