Film capacitors are fundamental components across many electronic applications. These include providing power filtering and acting as a both static capacitors and dynamic capacitors in oscillatory or resonant circuits. B32922C3473K000 is a popular film capacitor within the wide range of film capacitors manufactured by TDK. In this article, we will discuss the application field and working principle of the B32922C3473K000.

The B32922C3473K000 is a low-capacitance, X2-class, polyethylene naphthalate (PEN) film capacitor. It is most commonly used in power supply applications such as motor drives and power supplies for LEDs. It is also used for energy storage and low-profile resonant oscillator circuits due to its low profile and robust construction. The capacitor is available in a standard 0.22uF size, as well as other sizes ranging from 0.15uF-27uF.

The B32922C3473K000 offers excellent long-term stability and high performance over wide temperature extremes. It operates with a temperature range of -40 degrees Celsius to +105 degrees Celsius and has a rated ripple current of 4 mA. The capacitor is available in a range of voltage ratings from 300V to 1000V. In addition, the component is extremely reliable with a rated life of 300,000 hours at 105 degrees Celsius.

The operating principle of the B32922C3473K000 is relatively straightforward. Like all capacitors, it stores electric charge and releases it when needed. This stored electric charge is stored in an electric field between two conductive plates. In the case of the B32922C3473K000, these are two metalized PEN films with an insulating material between them. On either side of these metalized films is a thin protective coating. When the electric field between these two metalized plates is changed, the capacitor will react, allowing electric current to flow or be stored.

The film capacitors have many advantages compared to other capacitor types. They have good dry self-healing and inverse current capability, which makes them extremely reliable. They also have very low losses, making them ideal for high frequency applications. In addition, film capacitors are very stable in high temperature applications as well as in the presence of high voltage.

As the demand for reliable and efficient power supplies continues to increase, the use of film capacitors such as the B32922C3473K000 is likely to become even more important. The low profile, high voltage rating and long-term stability of this component make it a great choice for many electronic applications. Along with the other advantages of film capacitors, this component is set to become even more widely used in the future.
