ECW-FD2J274K

Film Capacitors

Film capacitors, also called nonpolarized capacitors, are divided into two categories: organic polymer film capacitors and metallic film capacitors. These capacitors are constructed with different types of plastic films, metals and ceramic materials, and they all serve the same purpose-to store electric energy. The ECW-FD2J274K is a film capacitor which includes a ceramic capacitor lead, and an epoxy body.

Application Field

The ECW-FD2J274K film capacitor finds use in many different fields, such as in automotive applications, control systems and power supplies. Automotive uses include ignition systems, distributorless ignition systems, anti-lock brakes and air bags. In addition, they are also used in the broadcasting, telecommunications and entertainment industries. These components are also found in motor control systems, high voltage motor drives, alternating current supplies and voltage regulation.

Working Principle

Film capacitors, such as the ECW-FD2J274K, are nonpolarized capacitors and are constructed from two electrode plates. One electrode plate is made from an aluminum foil. An insulating or dielectric material is placed between these two electrodes. This dielectric is usually made from plastic, waxed paper or an inorganic material.

When a voltage is applied across the two plates, an electric field is established within the dielectric material. This electric field produces an electrical capacitance, which is measured in Farads. This capacitance is proportional to the size of the plates, the area they occupy and the dielectric material used. The ECW-FD2J274K film capacitor has a capacitance of 2.7 to 4.7 μF.

Film capacitors are also used in circuits, as they allow for the release of the charge stored in them when the voltage is released. This release can be useful for quickly discharging a voltage source to avoid a possible electrical spike in the circuit.

In addition to their use in circuits, film capacitors are also routinely used in wave filters, DC blocking, power factor correction and bypassing. They can also be used in AC power supplies and power controllers, as they help to obtain the desired current waveform.

The ECW-FD2J274K film capacitor is well-suited for use in a variety of commercial applications. Its epoxy body and ceramic capacitor lead provide good insulation, making it resistant to shock, vibration and water. Its small size also makes it suitable for use in tight spaces. The ECW-FD2J274K film capacitor\'s long service life allows it to provide reliable performance for years.
