Film capacitors are passive electronic components that store electrical energy in an electric field. They are constructed using thin plastic films as the dielectric material, which is sandwiched between conductive layers. This design allows film capacitors to exhibit excellent electrical characteristics, making them suitable for a wide range of applications, from consumer electronics to industrial machinery.
Product standards play a crucial role in ensuring the reliability, safety, and performance of electronic components, including film capacitors. These standards provide guidelines for manufacturers, helping them produce components that meet specific quality and performance criteria. Adhering to established standards not only enhances product quality but also fosters consumer confidence and facilitates international trade.
