Film capacitors (also referred to as plastic film capacitors) are broadly used electronic components. B32653A1473K189 is a kind of film capacitor, and their application field and working principle will be discussed in the following article.

Film capacitors, as the name implies, is a kind of capacitors which makes use of a thin plastic dielectric film. It is of low cost, low loss and high insulation resistance with temperature and frequency. Thanks to these characteristics, film capacitors are widely used in power electronic circuits, electrical circuits, radio-frequency circuits and so on.

B32653A1473K189 film capacitors have been widely used in motor drives, frequency converters, power supplies, x-ray treatments, and general purpose and low frequency electrical circuits. B32653A1473K189 is a kind of strong film capacitor, with rated voltage as 300VAC/420VDC, capacity as 473uF and dielectric film as polyester.

The working principle of B32653A1473K189 film capacitor can be simplified into the following: when the capacitor is connected with direct current or alternating current, an alternating current primary charge occurs at one plate of the capacitor due to the surface effect. The charge will overflow and the opposite plate will have an equal intensity of opposite sign charges. Then due to the high dielectric resistance between the two plates, the charges will be blocked and stored, forming an electrostatic field which is responsible for the capacity of the capacitor. The distance between the two plates and the thickness of the dielectric film will greatly influence the capacitor\'s capacity.

In conclusion, B32653A1473K189 is a film capacitor, belonging to the broader category of plastic film capacitors. Thanks to its low cost, low loss and high insulation resistance with temperature and frequency, B32653A1473K189 film capacitors have found applications in multiple areas, especially motor drives, frequency converters, power supplies, x-ray treatments, and general purpose and low frequency electrical circuits. And of course, its working principle is to use the alternating current primary charge to form electrostatic field.
