Film Capacitors

Film capacitors, also known as film dielectric capacitors, are electronic components that rely on an insulating film for their functioning. Their name is derived from the thin dielectric film coating used on their electrodes, which acts as a dielectric material. The thin metal layer on the electrodes acts as an electrical conductor. The electric charge is stored in the thin film layer due to the attractive force between the thin metal layers. This electric charge can then be released upon application of an electric current.

474PSB102K4H is a film capacitor which is used in a wide range of applications. It finds application in consumer electronics, signal processing, medical, military and aerospace systems. It has a maximum voltage rating of 470V and a capacitance between 1uF and 1K up to 500V DC. It is also available in an array of package sizes.

The working principle of 474PSB102K4H is based on its design. Its electrodes are made of a thin metal layer deposited onto an insulating film. This film acts as a dielectric material and stores electric charge. When an electric current is applied across the electrodes, the stored electric charge is released. The electric field created between the electrodes allows current to flow between them, and this in turn creates an electric current.

The metal layers of the film can vary in thickness depending on the application. Typically, for high voltage applications, thicker metal layers are used. The thicker the layers, the larger the capacitance of the capacitor. For low voltage applications, thinner metal layers may be used to reduce the capacitance of the capacitor. Additionally, the dielectric films used can also vary depending on the application and the voltage rating.

The 474PSB102K4H film capacitor finds broad use in consumer electronics and signal processing, owing to its favourable capacitance to volume ratio. It is also used in medical, military and aerospace systems since its size and capacitance rating are very suitable for these types of applications. It offers good electrical performance at wide temperature ranges and is also self-healing, meaning it can repair itself in case of damage.

In conclusion, 474PSB102K4H is a versatile film capacitor which finds broad use in a variety of applications. It is renowned for its performance under harsh conditions, its small size and its wide range of capacitance ratings. Its working principle is based on the attractive force between thin metal layers deposited onto an insulating film, which act as electrodes and store electric charge.
