The development of Power over Ethernet (POE) technology is very strong. The development of this technology can simplify the installation and deployment of electrical equipment, thus eliminating the need for independent transmission lines. Nowadays, power supply technolog...

No matter which method is used to achieve network port communication, it cannot be separated from relevant standard protocols. However, the Ethernet involved in our company's ONU product series mainly follows the IEEE 802.3 standard. Below is a brief introduction to the ...

TVS - Short for Transient Voltage Suppressor Diode. TV is a voltage limiting overvoltage protection device in the form of a diode. When the two poles of TVS are subjected to reverse transient high-energy shocks, it can convert the high impedance between the two poles int...

As a protective device, TVS tubes can effectively prevent electrostatic breakdown and protect circuits. When selecting TVS tubes, attention must be paid to their relevant parameters, otherwise unexpected problems may occur. VRWM, VBR, Vc, Ipp, Cd are important parameters...

How to determine the three poles first? The identification of the three pins on the MOS transistor symbol should focus on key points: G-pole, needless to say, is relatively easy to recognize. The S-pole, whether it is a P-channel or an N-channel, intersects two lines. D-...

The through-hole itself has parasitic capacitance to the ground. If the diameter of the isolation hole on the floor layer of the through-hole is known to be D2, the diameter of the through-hole pad is D1, the thickness of the PCB board is T, and the dielectric constant o...
