FAQ about Film Capacitors
-
1. What are the uses of film capacitors?
High-frequency filtering, power decoupling, power noise bypass
The main uses of film capacitors include high-frequency filtering, power decoupling, power noise bypass, etc. In electronic devices, film capacitors are widely used in various circuits due to their high insulation impedance, wide frequency response and self-healing properties.
Specific application scenarios
High-frequency filtering: Film capacitors have excellent high-frequency insulation performance, and the capacitance and loss angle are independent of frequency in a large frequency range and change little with temperature, so they are often used in high-frequency filtering circuits.
Power decoupling: In car audio systems, film capacitors are used for power decoupling to ensure stable power supply and avoid noise caused by feedback generated by the power supply.
Power noise bypass: Film capacitors are also widely used for power noise bypass (reverse cross-connection) to reduce the impact of power noise on the circuit.
Different types of applications
CBB film capacitors: widely used in circuit boards because of their high insulation impedance and wide frequency response.
Organic film capacitors: Made of materials such as polypropylene film and polyester film, they have excellent performance, a wide variety of varieties, and a wide range of applications. They are suitable for a variety of electronic devices.

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. 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.
