Film Capacitors

Film capacitors are widely used in a variety of different applications. This section will provide an overview of the various applications of film capacitors, as well as their working principles. Specifically, we will discuss the 473PPB400K model of film capacitor in detail.

Applications of Film Capacitors

Film capacitors are used in many different applications, from consumer electronics to industrial environments. They are increasingly being used in high frequency power supplies, as they have excellent frequency-temperature characteristics. They can also be used in power supply filtering, along with other types of capacitors for a better quality of output. In addition, they are used in DC-DC and AC-DC converters. Many consumer electronics, such as personal computers, cell phones, and digital cameras, also rely on film capacitors.

Film capacitors are ideal for use in high-reliability, high-temperature applications. They are resistant to arcing, and their insulation requirements make them suitable for use in high-voltage circuits, particularly in applications that require high peak-to-peak voltages or large current supplies. Furthermore, their film construction allows for very low self-inductance, which is beneficial in high-frequency, low-power applications.

Another key application of film capacitors is in automotive electronics. Their excellent temperature range and resistance to arcing makes them an ideal choice for use in engine control units, fuel delivery systems, and other under-the-hood components. Additionally, they are found in audio systems, as they are ideal for storing and conditioning signals. Film capacitors are also used for SMPS and ac-threshold applications.

Working Principles of the 473PPB400K Model

The 473PPB400K film capacitor is a popular choice for many different applications. It is an axial-leaded capacitor with a voltage rating of 400 volts. It has a capacitance of 15µF and a tolerance of ±5%. It has a maximum working temperature of 125°C, and it has a dielectric strength of >1,500V/µs.

The 473PPB400K is a polyester-polycarbonate film capacitor. It uses a film of polyester-polycarbonate as its dielectric insulator, and its electrodes are made of aluminium foil. The combination of the two materials allows for a higher voltage rating than other types of film capacitors. The metal foil and pieces of carbon-based film are rolled up, forming the capacitor. The package of the 473PPB400K has the following dimensions: 15.8 mm x 8.3 mm.

The 473PPB400K provides excellent reliability and high levels of performance. Its high performance is due to its film construction, which gives it excellent temperature characteristics and improved reliability. It has a wide operating temperature range and is resistant to arcing, which makes it an ideal choice for high-voltage applications. In addition, its low inductance makes it suitable for use in high frequency applications. Overall, the 473PPB400K is an excellent choice for many different applications.
