    Re: Identify an electronic component

    If you aer not sure about what kind of component it is, so check what devices are surrounding this one to have an insight of its function on the circuit, as for example if it is in series or parallel with something, if it is in the input or output circuitry, etc...no need to make a deep survey.

    Re: Identify an electronic component

    Judging by the proximity to B- , it appears to be a low side Nch FET current switch perhaps <50 mOhm.
    A best design is easily achieved with good test specs™
    A better question deserves a better answer. ™
    ... so include all your acceptance criteria ( values, % tolerance) and assumptions in your question or any design.
