The role of CBB capacitor in circuit

1, CBB capacitor applied to the function of signal circuit, transistor amplifier emitter has a self-bias resistance, it also makes the signal generated voltage drop feedback to the input to form the input and output signal coupling, this resistance is the coupling of the components, if the resistance at both ends of a parallel capacitor, due to the appropriate capacity of the capacitor on the AC signal smaller impedance, This reduces the coupling effect generated by the resistance, so it is called the decoupling capacitor.

2, CBB capacitor is actually a polypropylene capacitor, which is a metal foil as an electrode, and the polypropylene film is overlapped from both ends and wound into a cylindrical structure of the capacitor. Non-polarity, high insulation impedance, excellent frequency characteristics (wide frequency response), and low dielectric loss. It is widely used in resonant circuits, bypass circuits and high frequency and high voltage circuits. Once the CBB capacitor fails, it should stop running immediately, otherwise it will have serious consequences.
