Audio circuit principle The dual-tone multi-frequency signal decoding circuit is an integrated circuit widely used in key telephones (fixed phones, mobile phones), program-controlled switches, and wireless communication equipment. 1. Dual audio decoding electronic circuit 2. Pin 3 receives the dual-tone multi-frequency pulse signal from the phone. The dual-tone multi-frequency signal is first passed through its internal [...]
Please check the ceramic capacitor manufacturing process: 💥Silver Paste Spraying 👉Silver Paste Spraying is one of the methods for coating electrodes in ceramic, glass, mica and other inorganic dielectric capacitors. Its working principle is through spray paint, which uses 4 to 5 atmospheres of compressed air to spray silver paste on the surface of the medium [...]
How to charge a farad capacitors The voltage-sharing resistor is connected in parallel at both ends of the capacitor, and then connected in series. After one of the capacitors is charged, it is similar to an open circuit, but because the resistor is still connected in the loop, the voltage across the [...]

47μF100V capacitors are generally aluminum electrolytic capacitors. This type of capacitor has poor high frequency performance and unstable capacitance. Electrolytic capacitors with a withstand voltage of 100V are generally large in size. Such capacitors are generally used in circuits. High-voltage filter capacitor or coupling capacitor. Although some ultra-low frequency oscillation circuits or timing circuits use 47μF [...]
