Film capacitors, or plastic film capacitors, are one of the most commonly used and reliable types of capacitors available for electric design applications. They are constructed from multiple layers of film that is dielectric and very thin, typically sandwiched in between two metal plates that create an electrical contact. The two metal plates also provide the necessary conductivity. The dielectric material is usually polyester, polystyrene, polycarbonate or polypropylene. Film capacitors are available in many different sizes and shapes, with various dielectric materials and metal coating materials.

R73UI0470SE03J Application Field and Working Principle

The R73UI0470SE03J is a radial film capacitor that is ideal for switching power supply applications, as it provides a stable capacitance over a wide range of temperatures and voltages. This product is designed mainly for car audio, television and VCR applications, and is offered in two versions: one with a radial leads, and one with axial leads. The R73UI0470SE03J has a rated voltage of 16V (DC) and a maximum operating temperature of 105°C.

The working principle of the R73UI0470SE03J is based on the principles of a parallel-plate capacitor. When a voltage is applied across the plates, an electric field is established and charge accumulates on the plates, which increases the capacitance. The capacity of the film capacitor depends on the thickness of the dielectric film, the area of the plates and the gap between them. This product offers a wide capacitance range from 0.001 μF to 220 μF.
