The ECQ-UAAF155M is a film capacitor that has a wide range of application fields and working principles which make it a very popular choice for many projects.

The ECQ-UAAF155M is a multi-layer polyester film capacitor which is a non-polarized, convex-shaped dielectric device. It is primarily used in a range of AC applications, including filter enhancement and coupling, clipping, RC-oscillators, and snubbers.

The ECQ-UAAF155M is composed of film dielectric layers that alternate with metal foil electrodes. These electrodes cover the whole capacitor surface, minimizing the risk of an internal breakdown. The polyester film used in the construction of this capacitor is extremely reliable, and provides high insulation resistance. The film itself is also very resistant to environmental and temperature changes, making it highly reliable in a wide range of applications.

The capacitance value of the ECQ-UAAF155M is determined by the amount of film layers used in its construction. The capacitance value can be calculated by taking the following values: the dielectric constant (K); the electrode surface area; the distance between the electrodes; and the film thickness. The more layers used, the higher the capacitance value of the device.

The ECQ-UAAF155M has a wide range of application fields, including consumer applications, industrial, railway, and automotive. It is used for high frequency filtering, power factor correction, and in surge arrester applications. Additionally, it can be used for high load start-stop and temperature compensating applications.

The ECQ-UAAF155M operates using a variety of principles, such as AC voltage, current, electromagnetic, and thermal. When a voltage is applied to the device, the electric field generated causes a polarization in the dielectric material, creating a capacitance. This allows the power to flow in an alternating current application.

The ECQ-UAAF155M also utilizes an internal damping effect which inhibits changes in the aforementioned electric field. This enhances the smooth flow of power, and reduces the risk of short circuits in surrounding components.

In summary, the ECQ-UAAF155M is a popular film capacitor which offers a wide range of application fields and principles. It is composed of multiple dielectric layers with metal foil electrodes, allowing it to withstand sudden voltage increases and providing reliable operation in a variety of applications.
