Application of patch capacitance in sound circuit (II)

The principle of tantalum capacitance is such that tantalum pole is easy to oxidize in air, people use its oxide film as medium, because tantalum pole is easy to oxidize, so tantalum capacitor has automatic "healing wound" repair effect, so it is durable and high reliability. Because the oxide film is very thin, the tantalum capacitor has a very close distance between the two plates, so it has no inductive reactance and is very sensitive, so the charge and discharge speed is fast. These characteristics determine that tantalum capacitors are suitable for high frequency, small current, and fast response circuits, so tantalum capacitors are also widely used in fast response and high reliability circuits, such as missiles and satellites. Tantalum capacitor is very sensitive, charging and discharging fast, so it is also used in high audio audio circuit, mainly high audio circuit. Because of reducing the loss of high frequency and weak current, it improves the sound quality and improves the sound quality.
