FAQ about Film Capacitors
-
1. 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.

2. Will the performance of film capacitors degrade?
Yes
The performance of film capacitors will degrade. The performance degradation of film capacitors is mainly due to their internal structure and material properties.
Reasons for performance degradation
Metal plating oxidation: During the capacitor manufacturing process, there is a trace amount of air between the film layers, which may be ionized under the action of the electric field to produce ozone. Ozone is a strong oxidant that oxidizes the metal plating to produce non-conductive metal oxides, resulting in a reduction in the plate area and a decrease in the capacitor capacity.
Humid air: During the winding process of film capacitors, if the workshop environment is not properly controlled, there will be a large amount of humid air. These humid air will produce air ionization reactions when the capacitor is working, generating ozone, which further causes the capacitor capacity to decay.
Poor quality materials: The film materials used are of poor quality, such as uneven evaporation and defects on the film, which will cause the capacitor capacity to decay.

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.
