Film capacitors are an important type of capacitors, featured by its small size, light weight, high frequency characteristics and low loss despite its relatively low capacitance. The ECQ-E10393KFB is a type of film capacitor specifically used for power supply applications, used in home appliances, lighting equipment, power tools, etc. It meets the requirements of: UL, CSA, VDE, RoHS, and REACH.

The ECQ-E10393KFB has a voltage rating of up to 250V AC and a capacitance range of 0.0047µF to 330µF. It has a temperature range of -40 degrees Celsius to 105 degrees Celsius, and a relatively low humidity humidity of up to 80% RH at a maximum.

The main features of the ECQ-E10393KFB are its low ESR, low inductance, and low dissipation factor. It is an electrolytic capacitor, which means that it is an AC capacitor, producing alternating current when voltage is applied across its terminals. The ECQ-E10393KFB also has a small size and high reliability, due to its metalized PET film construction.

The working principle of the ECQ-E10393KFB is based on the theory of capacitance. When an AC voltage is applied to the ECQ-E10393KFB, the current flows from the positive terminal to the negative terminal. The electric field between the plates of the ECQ-E10393KFB creates a capacitance, storing and releasing the energy as an AC current. This AC current can be used for various power applications such as in lighting and power tools, and reduces the risk of overloading or damaging the device.

The ECQ-E10393KFB also features a self-healing effect. This is important in preventing damage due to prolonged exposure to high temperatures or high voltage. When the ECQ-E10393KFB is subjected to high temperatures, pressure, or voltage, its metalized PET film construction causes the metal strips on the film to expand, closing any holes which may have formed in the dielectric material. This prevents further damage or leakage of the energy stored in the capacitor. Additionally, the ECQ-E10393KFB has a very long life expectancy, lasting up to 10000 hours or more when used in normal conditions.

In conclusion, the ECQ-E10393KFB is a film type capacitor specifically designed for power supply applications, with features such as its low ESR, low inductance, and low dissipation factor. It can be used in home appliances, lighting equipment, and power tools, and is ideal for applications requiring a reliable power supply. Its working principle is based on the theory of capacitance, and its metalized PET film construction improves its reliability and also helps to protect the capacitor from damage due to high temperatures, pressure, or voltage.
