Hello everyone, when we design Ethernet products, we often see that the bottom of the Ethernet transformer is hollowed out. I would like to discuss the purpose of this hollowing out and what harm it w
The circuit is connected as shown in the figure. Is the waveform measured at the blue test point related to the resistance and capacitance on both sides? Will the resistor R3 affect the waveform ampli
After the spot welding is turned on once, there is no current output. And the capacitor voltage is pulled down to 1v, and it slowly rises back to the original voltage after releasing the welding pen.
