What types of semiconductor diodes can be classified according to their construction?

Leave a Comment / Varactor diode / By huanggs

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. So what types can it be classified according to its construction? Follow Xiaobian to have a look ~ ⒈ Dot contact …

Understanding capacitor elements

Leave a Comment / Electronic / By huanggs

The Capacitance, also known as the Capacitance, refers to the charge storage at a given potential difference. The symbol is "C". The SI unit is Farad. The commonly used capacitance units are millimetric (mF), micrometric (μF), nanometric (nF) and cuticle (pF). The specific conversion method is as follows: 1 farad (F) =1000 milieu (mF) =1000000 …

Metal stamping process classification

Leave a Comment / furniture / By huanggs

The Hardware stamping process can be divided into two categories: hot stamping and cold stamping. Metal stamping hot stamping is to heat metal materials to a certain temperature range of stamping processing method. The characteristics of hot punching are: can eliminate internal stress, avoid work hardening, increase the plasticity of materials, reduce deformation resistance, reduce …

Do you know the reflection principle of terminal resistance signal?

Leave a Comment / Varactor diode / By huanggs

During communication, there are two causes of terminal resistance signal reflection: impedance discontinuity and impedance mismatch. Impedance discontinuity, the signal at the end of the transmission line suddenly meets the cable impedance is very little or no, the signal will cause reflection at this point. The principle of signal reflection is similar to the way …

What is terminal resistance?

Leave a Comment / Varactor diode / By huanggs

What is the terminal resistance? Terminal resistance is an obstacle encountered in the transmission of electronic information. When high-frequency signals are transmitted, the signal wavelength is shorter than that of the transmission line, and the signal will form reflected waves at the terminal of the transmission line, interfering with the original signal. Therefore, terminal resistance …

What are the differences between the four common resistors?

Leave a Comment / Varactor diode / By huanggs

Today Xiaobian to introduce the difference between the following four kinds of resistance: 1, insulation resistance A DC voltage is applied to the medium. After a certain time of polarization, the corresponding leakage current through the dielectric is called insulation resistance. Insulation resistance is the most basic insulation index of electrical equipment and electrical circuit. …
