    What cases to use slots/cutouts in PCB and based on which parameters we deduce their dimentions!?

    Hello all, I am designing a PCB that contains some relays, so I decided to use cutouts to separate relay's contacts (depicted by green in image below) and maybe Neutral/line based on what I have seen in some PCB designs... my questions are: what is the purpose of cutouts/slots other than...

    Buffer a high Voltage

    Hello, In my design I need to buffer about 45V-48V and about 30V. For this purpose I want to use two Opamps in Unity Gain Configuration and chose to use 2 ADA4522 (since it has an input range of 0-55V and low a low offset voltage, see attached schematic). In the simulation the buffer circuit...

    What is this doing with only three wires

    ok i know its a step-up transformer that i pulled from an electric mouse trap for the life of me i can't figure out how the bloody heck they get the thing to step up or work at all I've dissected a couple and it would appear to be a layered step-up transformer the blue and black are the primary...
