FAQ about Film Capacitors
-
1. Are film capacitors suitable for audio?
Suitable
Film capacitors are very suitable for audio applications. Film capacitors perform well in audio circuits and have the following advantages:
Non-polarity: Film capacitors have no positive or negative poles, which gives them greater flexibility in circuit design.
High insulation impedance: The insulation impedance of film capacitors is very high, which can effectively reduce leakage current in the circuit and improve the stability of the circuit.
Excellent frequency characteristics: Film capacitors have a wide frequency response and can provide stable capacitance performance in the high and low frequency ranges, which is suitable for various frequency changes in audio circuits.
Low dielectric loss: The dielectric loss of film capacitors is very small, which means that during the transmission of audio signals, less energy is lost and the integrity of the signal is maintained.
Self-healing properties: Film capacitors have self-healing properties and can automatically repair internal defects when they occur, extending their service life. -
2. How do film capacitors fail?
High working environment temperature, improper selection of working current, exceeding the specified working voltage, harmonic current
The main reasons for film capacitor failure include the following:
High working environment temperature: Film capacitors can work normally in a temperature environment of -40℃~+105℃, but exceeding this range will accelerate thermal aging, resulting in a shortened service life, and even bursting in severe cases.
Improper selection of working current: The current value in the circuit should be less than the current value allowed by the film capacitor, otherwise it will cause the capacitor to heat up, and long-term use will shorten the life, and even burst in severe cases.
Exceeding the specified working voltage: Excessive voltage will cause partial discharge, which will then break down the capacitor and cannot be used.
There are harmonic currents: high-order harmonic currents are superimposed on fundamental currents, resulting in an increase in total current, causing capacitor load overload, internal expansion, and explosion.
Buying inferior capacitors: In order to reduce costs, some manufacturers on the market use low-quality materials to produce capacitors, which greatly reduces the actual withstand voltage and life of such capacitors.
The structural characteristics of film capacitors and the impact of the use environment on their performance:
Film capacitors are usually composed of polypropylene film, aluminum foil and plastic shell. Polypropylene film is sensitive to high temperature, which accelerates its aging and shortens the life of the capacitor. In addition, a humid environment will also cause water vapor to enter the capacitor, affecting its performance.

3. 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.
