ECQ-E6393JFB

Film Capacitors are an important class of electronic components used in a variety of electronic applications. The ECQ-E6393JFB is a high-quality film capacitor that is especially suitable for applications such as AC line filtering, audio signal coupling, and bypass/blocking in DC circuits. This article provides an overview of the ECQ-E6393JFB\'s application field and working principle.

The ECQ-E6393JFB is a polypropylene film capacitor with excellent performance characteristics such as high insulation resistance, high dielectric strength, and excellent temperature stability. Its rated voltage is 630 VDC, and its tolerance levels are within ±10%. Additionally, this product features a long life of 3000 hours at full rated temperature of 65°C and humidity of 85%.

This product is particularly suited for applications such as AC line filtering, motor start/run /stop, and audio signal coupling, due to its impressive performance characteristics. When used in AC line filtering, it helps protect circuitry from the RFI (Radio Frequency Interference) of 30MHz and above. This is accomplished by blocking any unwanted RFI that may be present in the AC line, and providing a clean power supply for other components in the circuit. Similarly, it also helps reduce noise and hum in audio signal systems by providing a high-impedance coupling between the signal source and the audio device.

The working principle of the ECQ-E6393JFB is based on the principle of capacitance and dielectric nature of certain materials. The product uses two thin plates that are separated by a thin layer of dielectric film. When a voltage is applied across the two plates, a field is created that stores electric charge on the two plates. This electric charge is then released when the voltage is removed, creating a current in the circuit. Similarly, the product can also block direct current, allowing it to be used for applications such as DC blocking.

In summary, the ECQ-E6393JFB is a high-quality film capacitor that is suitable for a number of applications. Its performance characteristics make it ideal for use in AC line filtering, motor start/stop/run, and audio signal coupling. Additionally, it is based on the simple principle of capacitance and dielectric nature of materials, making it a reliable and long-lasting product.
