Production Process
FAQ
Why is there a tolerance value for the capacitance of a capacitor?
Because with the current technology, it is impossible to ensure that the capacitance of each capacitor is exactly the same as the design value (nominal value) during the production process, and there is always a certain deviation, that is, the tolerance of the capacitance of the capacitor (error). The error of the capacitance of capacitors is mostly expressed as a percentage. J: ±5%, K: ±10%, M: ±20%. It is the same case for the resistor.
What is the time constant of a capacitor?
The capacitor itself has no time constant. Only when the RC circuit is formed with a resistor, there is a time constant of this number.
The product of the capacitance of the capacitor and the resistance value is the time constant of the RC circuit. The larger the time constant, the slower the charging speed, the longer the transition process, which is the physical meaning of the time constant.
