    La-c701p

    Hi All
    I have a mainb HP LA-C701P which has exploded the mosfet Q30
    and once unsoldered the rubble of the mosfet I found a short to ground of the DRAIN
    not having any serigraphy in the pcb I can't determine the value of this capacitor to which I post the photos, this capacitor is shorted to ground.
    I tried to measure the size of the component and for me it is a 0804 while in the wiring diagram if that turns out to be a C590 the specifications tell me that the component is from the 0402 family

    I ask for help and confirm if the capacitor in that position is the C590 or please someone tell me what it is associated with

    THANK YOU in Advatage

    That is a large cap. To me, looks to be an 0805 smd size.

      it seems to me too, but how do I identify it in the schema eleytrico and associate the value?

        This is a non-polarized ceramic cap.

        Use 1uf (or a bit higher will be ok) 0805 at 6v3 rating.

        Suggest X7R but X5R will be fine. This defines the capacitance over temperature changes.
