Film capacitors are the most commonly used type of capacitors for industrial applications. They are also referred to as plastic or polypropylene film capacitors, and are usually found in a faceted or flattened cylindrical shape with two metal electrodes. The ECW-H12242JVB is an example of a film capacitor, and is widely used in microwave ovens, high frequency circuits, switch mode power supplies and other electronic equipment.

Application Field of ECW-H12242JVB

The ECW-H12242JVB is a polypropylene, thin-film capacitor with a dielectric thickness of 1.2mm and a very low dissipation factor. It has an operating temperature range of -55°C to +125°C. Its capacitance and voltage ratings depend on the size, but range from 10pF to 22nF and 400V to 2000V, respectively. These values make the ECW-H12242JVB suitable for use in high frequency circuits, such as radio-controlled units, as well as in various types of automotive, industrial, consumer and audio/video electronic applications.

ECW-H12242JVB is also used in high-reliability applications, due to its stability, low parasitic inductance, and low total capacitance tolerance of 0.3pF. It is also typically employed in applications that require low-loss and low-dielectric absorption, such as in pulse discharging circuits, RF microelectronics, and high-speed signal circuits.

Working Principle of ECW-H12242JVB

The ECW-H12242JVB is a polypropylene film capacitor, which is composed of a polypropylene dielectric substrate with two metal electrodes. This type of capacitor works by storing electrical energy in an electrostatic field and then releasing the energy when the power supply is removed. There are several layers in the dielectric of the ECW-H12242JVB, each of which has a different thickness, allowing the capacitor to have a high capacitance value over a wide frequency range.

The electrodes of the ECW-H12242JVB are connected to the substrate using a conductive adhesive. The electrodes provide the required impedance, and the compound ensures that the current is carried evenly through the entire device. The amount of current that can pass between the two electrodes is then limited based on the dielectric constant of the medium.

The ECW-H12242JVB is a surface mount device that is designed to provide a high capacitance value for applications that require a low-loss, low-dielectric absorption. It also has a low impedance, making it ideal for pulse discharging circuits and high-speed signal circuits. This device is easily integrated into a circuit and can provide reliable performance for many years.
