As we all know, resistor is a common component in our work and life. It is generally known as resistance and is a current-limiting component. In principle, it is connected to the resistance in the circuit, the resistance value of the resistor is fixed, generally two pins, which can limit the current through its connected …

Switching power supply is mainly composed of two parts: power level and control level. The main task of power level is to choose different topological structure according to different application occasions and requirements, and consider the design cost of semiconductor components. The main task of the control stage is to select the appropriate control mode …

I. Reading method of ceramic capacitor 1. Method of representation of capacitor capacity The basic unit of capacitor capacity is "farad" (F), 1/1000000 (millionth) of 1 farad is 1 micromethod (μF), 1/1000000 of 1 micromethod is 1 PF (1 picomethod or 1 picomethod). The relationship between them is a million (or 10 to the sixth) …
