Film capacitors, also known as plastic film capacitors, are a type of capacitor characterized by their use of a thin plastic film as their dielectric layer. They are constructed by attaching ends of two conductive layers to the dielectric. These layers, most often aluminum foil, are rolled up into a cylindrical shape and then sealed in a plastic casing. Common types of plastic film capacitors include polyester, polypropylene, and polycarbonate. The ECQ-E12473KE is a film capacitor, and falls into the family of film capacitors.

The ECQ-E12473KE is a general-purpose, class X2, polyester film capacitor. The device is non-polarized, meaning it has no positive or negative polarity. This makes it suitable for use in a variety of applications, such as motor control, ac-dc converters, inverters, high-frequency power supplies, and other circuits where high-grade, low-ESR performance is desired. Additionally, the device has a higher ripple current rating, compared to other types of capacitors, which is important in applications with high frequency, analog, and power electronics.

The ECQ-E12473KE is a three-layer capacitor, which consists of an outer plastic casing, inner plastic film, and two layers of aluminum foil. The layers are wrapped tightly around a plastic core and then sealed with a plastic coating. This construction enables the device to withstand higher temperatures than an electrolytic capacitor and allows for higher operating voltages. The outer casing helps to protect the inner layers from moisture, dust, and other environmental factors. Additionally, the plastic film provides superior dielectric properties, compared to other capacitor types.

The working principle of the ECQ-E12473KE is based on the fact that oppositely charged particles in close proximity to each other attract and repel, which produces an electrical field. This field is then used to store electrical energy, allowing the capacitor to act as a circuit component. The working principle also applies to other types of capacitors, including ceramic and electrolytic capacitors.

The ECQ-E12473KE is an excellent choice for a variety of film capacitor applications. Its non-polarity, high ripple current rating, and superior dielectric properties make it suitable for use in a variety of applications, such as motor control, ac-dc converters, inverters, high-frequency power supplies, and other circuits. Additionally, the device’s construction helps to ensure reliable performance and long-term stability.
