Knowing the basics of inductance and capacitance are crucial for PCB designers. You already know that ICs need decoupling capacitors, but knowing why is a better nugget of knowledge. Knowing some ...

It’s something that [Ben] had a need for, which he solved with a clever combination of PCB material and 3D printing. While the variable capacitors of yore invariably used intersecting vanes on a ...

The mounting of the capacitor – C22 – matches the markings on the PCB. However, rather than a positive voltage, the positive marked terminal is connected to -5V from the power connector ...
