Film capacitors are a type of capacitor which utilizes a thin-film insulating material instead of plastic or ceramic plates. They are used in a wide variety of different applications and are generally a sought-after component due to their relatively low cost, reliability, and size. Some of the most common film capacitor applications include power supplies, motors and audio applications.

ECQ-E2273KFB is a film capacitor from Panasonic which is able to support switching power supplies and inverters in industrial applications. The capacitor has a voltage rating of 250V, a capacitance of 22 µF, and a nominal ESR of 0.237 Ohms. The part is made of a non-inductive type that has a radial lead with a phenolic resin case which can handle temperatures up to 105°C.

ECQ-E2273KFB is widely used in motor drives, power supplies, and audio applications, due to its reliability and low cost. The capacitor helps to reduce the ripple effect in switching power supplies and provides low ESR and high surge current protection. It can also be used to filter out noises in audio applications and helps to prevent distortion.

The working principle of the ECQ-E2273KFB is quite simple. In essence, this capacitor stores charge and releases it when required. When DC power is applied, the voltage across the capacitor increases, as the capacitor begins to store charge. When the voltage reaches a critical point, the capacitor discharges, and the stored charge is released. This process is known as dielectric polarization and is used to store electrical energy for a short period of time.

This capacitor is considered to be a reliable and cost-effective option due to its ability to store and release charge quickly. The capacitor is also capable of withstanding temperatures up to 105°C and is generally considered to be a robust component. In summary, the ECQ-E2273KFB is a reliable and cost-effective film capacitor which is suitable for a variety of industrial applications such as motor drives, power supplies, and audio applications.
