1. What is a paper film capacitor?
Paper film capacitors are actually a conceptual error because "paper film capacitors" are not a standard type of capacitor. Based on the information provided, you may want to ask about paper capacitors and film capacitors.
Paper capacitors
Paper capacitors are capacitors that use paper as a dielectric. It consists of thin paper as the dielectric and aluminum foil as the electrode, which is wound into a cylindrical shape and then impregnated with a shell or epoxy resin. Paper capacitors have the following characteristics:
Low cost: Paper capacitors are usually low-cost and suitable for mass production.
Large loss: Due to its material properties, paper capacitors have large losses.
Application scenarios: Mainly used for bypass, coupling, filtering, etc. in low-frequency circuits. -
2. Are film capacitors better than electrolytic capacitors?
Not necessarily
Film capacitors and electrolytic capacitors each have their own advantages and disadvantages, and the specific choice depends on the application scenario.
Advantages of film capacitors
Non-polarity: Film capacitors are non-polar, and there is no need to distinguish between positive and negative poles, avoiding the risk of capacitor explosion due to reverse connection.
Long life: Film capacitors have significantly longer life and better stability.
Wide temperature range: Film capacitors have a wide operating temperature range, generally -40℃~+105℃/110℃, suitable for various ambient temperatures.
High withstand voltage: Film capacitors can withstand overvoltages higher than 1.5 times the rated voltage in a short period of time, and have strong withstand voltage.
Low loss: Film capacitors have low loss and are suitable for high-frequency circuits, especially for occasions requiring low loss and high-frequency applications.
Advantages of electrolytic capacitors
Large capacity: Electrolytic capacitors usually have large capacitance and are suitable for occasions requiring large amounts of energy storage.
Low cost: The cost of electrolytic capacitors is relatively low, suitable for occasions with strict cost requirements.
High energy density: Electrolytic capacitors are a strong choice when cost-effective, high-capacity energy storage is required, especially when maintaining DC output voltage during power outages.

3. What is the difference between foil capacitors and film capacitors?
Electrode materials, structure, and application areas
The main difference between foil capacitors and film capacitors lies in electrode materials, structures, and application areas.
Electrode materials and structures
Foil capacitors: Foil capacitors usually use metal foil as electrodes. This electrode is formed on a plastic film by vacuum evaporation, which is called a metallized film. This structure can save the thickness of the electrode foil, thereby reducing the volume of the capacitor and making it more miniaturized.
Film capacitors: Film capacitors use plastic films as dielectrics. Common plastic films include polyethylene, polypropylene, polystyrene or polycarbonate. These films overlap at both ends and are rolled into a cylinder to form a capacitor. -
4. What are the alternatives to film capacitors?
CL21 capacitors, MPB capacitors, CBB13, CBB81, MMKP82 capacitors
Alternatives to film capacitors mainly include CL21 capacitors, MPB capacitors, CBB13, CBB81 and MMKP82 capacitors. These alternatives have their own advantages and disadvantages in performance and applicable scenarios, and the specific choice depends on specific needs.
CL21 capacitors
CL21 capacitors and CBB22 capacitors can replace each other in applications such as filtering. CL21 capacitors are more stable than CBB22 capacitors under high-frequency conditions, so CL21 capacitors are more preferred in high-frequency circuits. However, CL21 capacitors are more expensive and perform better in high-frequency circuits.
MPB capacitors
MPB capacitors are boxed metallized polypropylene film capacitors with the same core as CBB22 capacitors, but with a plastic shell, which has better resistance to high temperature, moisture and sealing performance. MPB capacitors can replace CBB22 capacitors in high frequency, DC, AC and pulse high current applications, but their prices are relatively high.
CBB13, CBB81 and MMKP82 capacitors
These capacitors have a higher voltage resistance, up to 3000V, and are suitable for applications requiring higher voltages. However, they are also relatively expensive and larger in size.
