Film capacitors, also known as plastic film capacitors, are a type of capacitor, typically a dry type capacitor. They are constructed using a metallized-film dielectric, and are designed typically for AC applications. In contrast to electrolytic or tantalum capacitors, they have very low equivalent series resistance (ESR) making them an excellent choice for high frequency applications.

The ECQ-E10473RJF is an example of a film capacitor. It combines two technologies, metallized polyethylene terephthalate (PET) and metallized polycarbonate (PC). This combination allows for very small size, as well as higher voltage and temperature ratings compared to similar capacitors with PET alone. The size of the capacitor is just 10.3 x 4.7 x 1.4 mm (without leads), making it ideal for very compact applications such as consumer electronics or medical equipment.

The working principle of film capacitors is based on electrostatic field theory. When a voltage is applied to the capacitor, the dielectric material (PET and PC layers) creates an electrical field between the two metalized layers, which stores energy in the form of electrostatic field. This stored energy will be discharged when the capacitor discharges. The larger the capacitor, typically the higher the capacitance.

The construction of the ECQ-E10473RJF consists of a major constituent of metallized polyethylene terephthalate (PET) layer, with metallized polycarbonate (PC) layer The combination of these two layers allows for higher voltage and temperature ratings compared to similar capacitors with PET alone.

The ECQ-E10473RJF is an excellent choice for high voltage, high frequency applications. It has an insulation voltage of 1000V AC and a rated voltage of 630V AC. It also has a low ESR (Equivalent Series Resistance) and a high ripple current capability. This capacitor is ideal for applications such as telecommunications equipment, test & measurement instrumentation, and power supplies.

In conclusion, the ECQ-E10473RJF is a high performance film capacitor based on polyethylene terephthalate (PET) and polycarbonate (PC). It is ideal for high voltage, high frequency, and low ESR applications, making it the go-to choice for telecommunications equipment, test & measurement instrumentation, and power supplies. Its small size and high power capabilities make it an ideal solution for compact applications where size and performance are critical.
