Thin Film Capacitors
What are thin film capacitors?
Polypropylene film capacitors are usually used capacitors in the electronics component. They are composed of two or many pieces of minute plastic film, capable of charging electrodes as the dialect charges. When the voltage exceeds 500V, they can take the place of electrolytic capacitors in certain applications.
For all your electrical needs, Enrgtech Components offers a wide selection of capacitors, including these polypropylene film capacitors, in a range of capacitance, voltage ratings, and tolerances.
Types of polypropylene film capacitors
Polypropylene film capacitors come in two different major configurations. The kind of dielectric (insulating) material used can be used to identify them. Film foil, to start, consists of two metal foil electrodes spaced apart by two plastic layers. A plastic film serves as the dielectric in metalized film, which comprises two very thin layers of metallization. You can select different film materials for the dielectric layer to get the electrical properties you want, such as stability or the capacity to endure high voltage.
Which type of capacitor is best?
Ceramic capacitors in class 1 have the best stability and losses. They are more stable with variations in voltage and temperature and offer excellent tolerance and precision. Oscillators, filters, and demanding audio applications can be used in class 1 capacitors.
What are polypropylene film capacitors used for?
Polypropylene film capacitors are employed in a variety of electric applications due to the excellent tolerance and voltage resistance of these types of film capacitors. These comprise lighting ballast systems, switching power supplies, high voltage circuit applications, and circuits with high peak current levels. They are being used in the following applications.
- Electronic circuits
- Power circuits
- Power supply units
