Film capacitors are an important component used in electrical and electronic circuits, and their wide range of applications are necessary for the general purpose of the circuit. BN104E0684J is a ceramic film capacitor that has a wide range of applications, as well as a unique working principle. This article will discuss the application field of BN104E0684J and the working principle of the component.

As one of the most universal free film types, BN104E0684J cermet film capacitors have excellent frequency characteristics and stability, and are used in a variety of fields, mainly for industrial control, automotive electronics, telecommunication, instrumentation, general circuit stability, and AC-DC integrated circuits. In addition, it is widely used in low-frequency circuits, DC circuits, DC filtering loops, variable speed inverters, high-power and high-voltage converters, and design of their associate circuits. BN104E0684J is often used in the switching power supply circuit, which plays the role in filtering, bypassing, frequency setting, etc. There is almost no electric loss in the capacitor itself, which makes it one of the most common components used in a variety of industries.

In addition to its wide range of applications, the BN104E0684J ceramic film capacitor has a unique working principle. Its structure consists of a ceramic material and an aluminum foil served as the electrodes. The dielectric is in the form of a thin film. When the capacitor is working, a layer of insulating material between the two electrodes can prevent current from passing through and form a capacitor with its capacitance value. As mentioned above, the capacitance between the two electrodes can be adjusted by changing the thickness of the ceramic film and the size of the electrodes. It can also be adjusted by adjusting the relative position of the dielectric layers.

When the capacitor is working, an alternating voltage is applied on the electrodes. This induces an electric field between the two electrodes, resulting in a displacement current through the capacitor. The current is led in equal and opposite directions, and then attacks the electric field. When the current is the same, the polarity between the two is reversed, and it is discharged at the same time. The speed of this change is proportional to the capacity of the capacitor, and its higher capacity will increase the speed of the change. This is the cycle of charging and discharging of the capacitor.

In summary, BN104E0684J ceramic film capacitors have a wide range of applications and a unique working principle. The dielectric plate is a thin film that can be adjusted by changing the thickness of the ceramic material and the size of the electrodes, as well as the relative position of the dielectric layers when in operation. This structure enables the capacitor to achieve its optimal performance. The charging and discharging process of the capacitor is proportional to its capacity, and these characteristics make it a valuable component in the industry.
