In the circuit board, CBB thin film capacitors are basically essential, many people do not know, in the end CBB thin film capacitors what use?
Film capacitors belong to the most commonly used class of capacitors, its insulation impedance is particularly high, wide frequency response and also has no polarity, so thin film capacitors are often used in integrated circuit boards, analog circuits and other circuits. In practical applications, the role of CBB thin film capacitors is mainly the following:
Role one: to suppress electromagnetic interference from the power supply.
Application in power electronic circuits. Film capacitors are used there, mainly to act as a buffer of electrical current and clamps, resonant bypasses, and inhibit electromagnetic interference from the power supply.
Effect 2: Reduce impedance.
When the thin film capacitor is used as a bypass, it mainly plays a role in reducing the impedance of the DC bus and absorbing ripple current from the load, thus effectively suppressing the fluctuation of the DC bus voltage due to load mutation. When the device is used in a resonant converter, it can function as a resonant with inductors.
The core advantages of thin film capacitors
Its main equidistants are as follows: non-polarity, high insulation impedance, excellent frequency characteristics (wide frequency response), and very small media loss. Based on the above advantages, thin film capacitors are widely used in analog circuits. Especially in the part of the signal intersection, it is necessary to use capacitors with good frequency characteristics and very low media loss to ensure that the signal is transmitted without too much distortion.
