When it comes to CBB capacitors, there may be some strange, but when it comes to electrolytic capacitors, most people are familiar. Electrolytic capacitors are widely used and used as one of the mainstream capacitors, but they are gradually replaced by CBB capacitors. So why do CBB capacitors gradually replace electrolytic capacitors?
What do these two capacitors mean?
No polarity, high insulation impedance, excellent frequency characteristics (wide frequency response, and small dielectric loss). Based on the above advantages, thin film capacitors are widely used in analog circuits. Especially in the intersecting part of the signal, it is necessary to use capacitors with good frequency characteristics and very low dielectric loss in order to ensure that there is not too much distortion when the signal is transmitted. The dielectric constant is high, the volume is small, the capacity is large, the stability is good, and it is suitable to make the bypass capacitor. Polystyrene film capacitor, low dielectric loss, high insulation resistance, but high temperature coefficient, can be used in high-frequency circuits.
