Film capacitors are a type of capacitor constructed with a thin polyester or polypropylene film as a dielectric material and aluminum, polyester or polypropylene film as the electrode. Film capacitors are typically extremely reliable and stable, withstanding high temperatures and high voltage. The ECH-U1H471JB5 is a type of film capacitor that has a wide range of applications.

Applications

The ECH-U1H471JB5 film capacitor is a surface mount type capacitance device. It has a wide range of applications, such as in consumer electronics, computers, power supplies, home theater systems, and more. It can also be used in motor drives, power transmission, industrial control, and instrumentation.

The ECH-U1H471JB5 film capacitor is a polarized capacitor with a rated impulse voltage of up to 5kV. It is characterized by its relatively small size, low loss, and high capacitance. The capacitor’s wide operating temperature range allows it to operate from -55°C to +85°C with relative humidity from 5% to 95%. It also has low dissipation factor and low leakage current, making it suitable for use in electronic circuits.

Working Principle

The working principle of the ECH-U1H471JB5 film capacitor is based on its dielectric characteristics. It consists of a thin sheet of polyester or polypropylene film that serves as the dielectric material. The electrodes consist of aluminum, polyester, or polypropylene films. When an electric field is applied, the molecules become polarized, causing an electric current to flow within the thin film. This polarization effect produces the electrical charge necessary to store energy in the capacitor.

The capacitor’s dielectric constant determines its capacitance, which is measured in Farads. This parameter depends on the material used for the dielectric and the thickness of the film. The ECH-U1H471JB5 has a dielectric constant of 0.15. The low dielectric constant ensures that the capacitor is capable of storing large amounts of charge in a small form factor.

The ECH-U1H471JB5 film capacitor also features an impressive capacitance range of 0.47µF to 4.7µF. This parameter is dependent on the thickness of the polyester or polypropylene film. The voltage rating of the capacitor can reach up to 5kV, depending on the application.

The ECH-U1H471JB5 film capacitor is an ideal choice for a variety of applications in consumer electronics, computers, power supplies, home theater systems and many other electrical and electronic devices. Its wide operating temperature range and low loss allows it to function reliably in harsh environments. Additionally, its low dissipation factor and low leakage current make it a great choice for low-noise, low-power circuits.
