    Hello,
    we have problems with defining those 3 components from BOM:

    470 C-USC0603K C0603K CAPACITOR, American symbol OpenSrinkler DC_driver C0603
    What is this value 470? Is it: 470pf or 470nf or 47pf?
    —————————

    AP3400 BSS123 SOT23 N-CHANNEL MOS FET OpenSrinkler DC_driver
    We can’t find this component AP3400, there is only AO3400,
    can You please add more specific name for AP3400 or is it same as AO3400?
    —————————

    PCB-SGAP OpenSrinkler DC_driver
    is it a varistor? Can You please add more specific name for it?

    Thanks in advance 🙂

    Is it possible that AP3400 is AO3401 ?

    according to this description:

    The AO3400 combines advanced trench MOSFET technology with a low resistance package to provide extremely low RDS(ON). This device is suitable for use as a load switch or in PWM applications. The opposite P channel Mosfet is AO3401.

    Indeed that’s AO3400 and not AP3400. It’s a surface mount N-channel MOSFET. The P-channel counterpart is AO3401.

    470 is 470pF.

    PCB-SGAP is PCB spark gap — not a component itself, just a PCB thing.
