Film capacitors, also known as polyester capacitors, are created by placing a metalized layer of plastic film between two metal plates. They are widely used in electronic and electrical circuits for various purposes, ranging from audio filters in home stereo systems to radio broadcast equipment. The 21FD37175-F film capacitor is one example of a film capacitor that is used in many applications. In this article, we will explore the application field and working principle of the 21FD37175-F film capacitor.

The 21FD37175-F film capacitor is perfect for use in electronic circuits due to its high capacitance and long life rating. It features a low ESR rating, which allows it to dissipate virtually no heat, providing stable voltage levels in the circuit, even under extreme loads. It also has a high working voltage, low dissipation factor, and very low noise production, making it ideal for high sensitivity applications. The 21FD37175-F also offers excellent temperature and frequency characteristics, and can handle current up to five amps.

The 21FD37175-F film capacitor is found in many different types of electrical applications. It is used in power supplies, motor control circuits, charge pumps, RF power amplifiers, matrix switches, liquid crystal displays, and ADC circuits. It is also used in high-end hi-fi systems, home theater systems, digital audio/video systems, multimedia systems, and automotive audio systems. In all these applications, the 21FD37175-F helps stabilize voltage levels and filter out AC noise, resulting in superior sound and picture quality.

The working principle of the 21FD37175-F film capacitor is quite simple. The two metal plates are placed between two metalized layers of plastic film, and the capacitor stores electric charge on these two layers. This means that the capacitor holds the potential difference of the voltage on the two plates, and when voltage is applied, it creates electric energy to be stored in the capacitor. This energy is then discharged when the voltage drops, thereby maintaining the stability of the voltage level in a circuit.

In summary, the 21FD37175-F film capacitor is an excellent choice for many electronic and electrical applications due to its high capacitance and long life rating. It features a low ESR rating, high working voltage, low dissipation factor, and very low noise production, making it ideal for high sensitivity applications. It is used in power supplies, motor control circuits, charge pumps, RF power amplifiers, matrix switches, liquid crystal displays, and ADC circuits. Its working principle is based on storing electric charge on two metalized layers of plastic film, which then provide stabilization of the voltage and electrical energy within a circuit.
