    Hi Guys,

    Couldn't identify what component this is. Is the shape meant to be like this? Found this in a TV Power Supply Circuit.

    Thanks.

    It's an inductor.

    A continuance . . . . . .

    Moreover it is being a faster switching, high current inductor, of ~4.7 uh inductive value.
    If pulling the heat shrink covering for inspection, you would find the windings nestled down
    within a " dumbell " ferrite core.
    For enhancement of its magnetic coercivity-efficiency- Q, there is being a strong ceramic button
    magnet bonded on its far end.
    If this was found in an older CRT based television / monitor I would more likely suspect this to be
    utilized in the systems horizontal deflection circuitry, RATHER THAN in its power supply circuitry.

    The PS is likely a switching supply (by itself) or the inductor could be in a "switching regulator" portion of the PS. Texas Instruments has a whole series of Power Management devices that utilize switching methods.

    Thats a ROHS. name means its a time trial and component thats designed to do its job correctly and with a certain amount of stability and proper functioning.
    most ROHS are specially designed to meet ROHS specs. like a ROHS designed for a heavy wire system will be designed for that enviroment, but if you used a different ROHS of the same size designed for a light wire system, it would probably fry out.

    more bad/incorrect advice

    you need to read up on what RoHS means

    Steve is correct. It is an inductor.
