Film capacitors, also known as plastic film capacitors, are components that use a thin plastic film as a dielectric and are widely used in modern electronics. 32FB4404-F is a high-performance film capacitor, mainly used in audio equipment and other related applications. This product features a wide range of capacitance values from 0.047 to 0.15 microfarads, a peak voltage up to 3.5 kV, and a temperature range of -55°C to + 85°C. Its exceptional applications become crucial elements in the design of a variety of equipment, such as automotive audio systems, TV receivers and set-top boxes.

The composition of the 32FB4404-F film capacitor is mainly made up of a film dielectric, a rolled and tensioned metal foil electrode, and a dense epoxy resin coated with a sealing film. And its production process is divided into several steps: The first is to make a polyester film, the second is to apply aluminum or zinc electrodes, the third is insulation pressure, the fourth is sealing insulation, and the fifth is packaging. This production process has high cost performance to ensure reliability.

As for the working principle, it is simple. One side of 32FB4404-F is connected to the positive terminal of the power supply and the other to the negative terminal of the power supply. The plastic film dielectric is placed between the two electrodes and serves as an insulation barrier. When ac current flows through, the electrodes can store electrical energy in the form of an electrical field which is proportional to the voltage applied. The capacitor can pass its stored energy when the voltage applied to the electrodes abruptly changes. This is why it is most suitable for high frequency applications, such as audio signal processing.

In general, the 32FB4404-F is a high-performance film capacitor suitable for audio applications and other electronic equipment with strict performance requirements. It features better performance than other similar capacitors in terms of its temperature range, capacitance range, and peak voltage capability. It can withstand high peak voltages, and its wide temperature range allows greater reliability and stability. As a result, it is widely used in a variety of audio equipment and other related industries to provide effective performance solutions.
