Introduction
Film capacitors, also known as dielectric capacitors, are made of thin films of various materials such as polyester, polypropylene, polycarbonate, and polyester-poly carbonate. Film capacitors are known for their excellent electrical performance and low dielectric losses, and are widely used in various applications such as audio, video, RF, and other electronic circuit applications. 947D731K901BHMSN is a type of film capacitor, which has a wide range of uses in various industries, including telecommunications, medical equipment, automotive, power supplies, industrial electronic equipment, consumer electronics, and measuring instrumentation.Application Field
947D731K901BHMSN film capacitors can be used in a variety of applications, such as AC/DC and audio crossover filters, X-ray machines, flashlights, electro-magnetic interference (EMI) / Radio Frequency Interference (RFI) filters, neutral position sensors, high-pressure discharge equipment, eddy current testing equipment, high-frequency circuits, pulse circuits, and power supplies. These capacitors are also used in high voltage applications, such as high voltage power supplies, pulse generators, and high voltage inverters.Working Principle
947D731K901BHMSN film capacitors function by storing energy in a form of electrical charge. The electrical charge is stored between two metal plates, which are separated by a thin layer of dielectric material. When there is an electric field applied to the capacitor, the charges on the metal plates will be imbalanced, creating an electrical potential difference across the plates. This electrical potential will create an electric current flow in the external circuit. When the power supply is removed from the capacitor, the electrical charge on the plates will remain, thus providing a reserve of energy to the external circuit.Advantages of 947D731K901BHMSN Film Capacitor
As 947D731K901BHMSN film capacitors are made of thin, dielectric layers, they offer many advantages compared to traditional capacitors. Firstly, they have low parasitic losses, as opposed to electrolytic or ceramic capacitors. This means that when the power supply is removed from the capacitor, the stored charge will remain for longer, ensuring a consistent amount of energy is supplied to the external circuit. Secondly, they offer a high insulation resistance, meaning that the charge stored in the capacitor after the power supply is removed will be safe and not cause any potential for electrical shocks. Finally, film capacitors offer excellent frequency characteristics, making them ideal for applications, such as RF and audio circuits, which require pure, clean signals.Conclusion
947D731K901BHMSN film capacitors offer a variety of benefits and are well-suited for a wide range of applications. They have low parasitic losses, high insulation resistance, and excellent frequency characteristics, making them suitable for a variety of applications in power supplies, pulse generators, high voltage applications, audio and video crossover filters, and more. While other types of capacitors may offer similar performance, film capacitors are the preferred choice in most cases as they are smaller, more reliable, and have longer lifespans.
