The capacitor of the coupling circuit is called coupling capacitor. This capacitor circuit is widely used in resistor-capacitor coupling amplifiers and other capacitor coupling circuits to isolate direct current and alternating current.
The capacitor of the filter circuit is called filter capacitor. This capacitor circuit is used in power supply filtering and various filter circuits. The filter capacitor removes signals in a certain frequency band from the total. report.
The capacitor of the decoupling circuit is called decoupling capacitor.
By using this capacitor circuit in the DC voltage supply circuit of a multi-stage amplifier, the decoupling capacitor eliminates harmful low-frequency cross-connections between each stage amplifier.
Generally speaking, itThere is nothing wrong with the product and it will not break! Only the battery will be reduced! First of all, current batteries are made of positive aluminum ribbons and negative carbon ribbons, which contain lithium ions! Normal temperature will not affect it! But there is also a small amount of internals that will be lost if left for a long time, reducing battery life. Packing it in the refrigerator and freezing it can protect and improve battery usage and lifespan. I hope this helps...
