Film capacitors, also known as film dielectric capacitors, are polarised capacitors utilizing a thin plastic film with metallisation as the dielectric layer. The currently available film capacitors are made with polyethylene terephthalate (PET), polypropylene (PP) and poly-ether-ether-ketone (PEEK). These film capacitors are widely used in electronic circuits in order to regulate current or store electric charge. The 472PPR162KE film capacitor belongs to the polypropylene capacitor family.

This 472PPR162KE film capacitor has a capacitance of 162nF, a voltage rating of 630VAC, and a maximum operating temperature of 105°C. It is designed for surface mount and is small in size, measuring 4.7 x 2.5 x 2.1 mm. As a result, it is ideal for a wide range of applications that require high power density and small form factor. It is touch-proof for safety and is lead-free and halogen-free.

The working principle of the 472PPR162KE film capacitor is fairly simple. It functions as a non-polarised capacitor, which uses a thin plastic film (polypropylene) as the dielectric layer to provide a barrier between metal electrodes. To increase capacitance, thin layers of dielectric are layered between the electrodes, forming a sandwich-like structure. When the capacitor is exposed to an AC signal, the electric energy storage occurs in the form of electric field within the spacing between the electrode, with the dielectric material acting as the insulator.

The 472PPR162KE polypropylene film capacitor is suitable for a wide variety of applications. It is commonly used in automotive applications, switch mode power supplies, rectification circuits, automated power factor correction units, and mains-operated equipment. It can also be used in many consumer applications, such as LCD televisions, audio devices, and any other electronic devices that require a low-voltage and high-capacity capacitor.

The 472PPR162KE film capacitor has a superior performance compared to its ceramic counterparts, thanks to its high capacitance in small sizes, high ripple current, and high surge voltage rating. Moreover, its low losses make it suitable for use in high-frequency circuits. Therefore, the 472PPR162KE is becoming increasingly popular for its high performance and reliability in the modern electronic industry.
