Film capacitors, also known as polymer capacitors, are a family of capacitors that use film as the dielectric material instead of the typically used ceramic or electrolyte. There are many types of film capacitors available in the market, most of which offer advantages over other capacitor types. BQ014D0472J is a type of film capacitor and is used in a wide range of applications. In this article, we will discuss the application field and working principle of BQ014D0472J in detail.

BQ014D0472J is a general-purpose type of film capacitor with an operating temperature range of -40°C to +85°C. This kind of film capacitor is ideal for applications such as AC motor control, power supply, and audio filtering. It is characterized by excellent noise suppression and insulation performance. This film capacitor also has a low internal loss and high dielectric strength for reliable operation. The BQ014D0472J is available in a variety of packages, with sizes ranging from 1.1mm to 1.6mm thickness. The BQ014D0472J is available in both ceramic and plastic leaded packages, which makes it highly versatile for various applications.

The BQ014D0472J is a radial leaded film capacitor which uses a polypropylene dielectric material. The capacitor is formed by winding two layers of film together around a central core. The inner core is made of aluminum, and the outer core is designed to provide a good electrical insulation between the two windings. The two windings are connected to the terminals of the capacitor, which are separated by a plastic separator. This structure offers excellent capacitance and stable performance.

The working principle of the BQ014D0472J is based on the change of dielectric material\'s electric field strength with increase in frequency. The film capacitor has two terminals, one of which is connected to a fixed potential difference. When an alternating current (AC) passes through the film capacitor, the electric field strength of the dielectric material changes which induces an opposite voltage in the capacitor. This voltage determines the capacitance of the capacitor. The voltage magnitude and frequency-dependent characteristics of the film capacitor make it ideal for AC power applications.

In summary, the BQ014D0472J is a versatile and widely used film capacitor. It has a wide range of applications, ranging from AC motor control to power supply and audio filtering. Its excellent noise suppression and insulation performance make it perfect for these applications. The working principle of a film capacitor, which is based on the change of dielectric material\'s electric field strength with frequency, enables the capacitor to have a wide range of frequency-dependent characteristics which makes it perfect for AC power applications.
