Working Principle

ECQ-B1H101KF3 is a capacitor composed of a dielectric film and metal foil electrodes. The electrodes are made up of two layers of laminated thin metal foil with the dielectric film in between. It is connected in parallel with the electrical circuit, and works by accumulating charge on the two metal electrodes.

When the switch is open, the capacitor will block the current, so it is called a passive element. When the capacitor is connected and the switch is closed, current will flow to charge the capacitor. During the charging process, the capacitor will isolate the source from the load, thus preventing the direct current from flowing. Over time, the capacitor will be charged to a certain value and the current will stop. At this time, the capacitor itself is like an energy storage device, and the current between the source and the load will be blocked, which is the working principle of the capacitor.

In the application of the ECQ-B1H101KF3, it can be used as a filter capacitor and a blocking capacitor, which is like a barrier in a dangerous or forbidden area. It can also act as a circuit component to reduce current inrush, suppress harmonic current, store energy, and prevent voltage drop, etc.
