What can semiconductor diodes be classified according to their construction?

The semiconductor diode mainly depends on the PN junction and work. The point contact type and Schottky type, which are inseparable from the PN junction, are also included in the range of general diodes. Crystal diodes can be divided into: ⒈ Dot contact diode Point contact diodes are formed by pressing a metal needle on …

Common-mode inductor

Working principle of common mode inductor Common mode inductance In a circuit, when a differential mode signal passes through a common mode inductor, the magnetic flux produced by the differential mode signal in the core is equal in magnitude and opposite in direction. The net flux is zero, so the common-mode inductance to the differential …
