@dschizas that is reference designator L9100 which is a 250 ohm ferrite bead. You can get the package size by measuring the distance from one point to the other.

You will need to check why it blew the way it did. There should only be 12 Volt on that rail, so make sure you have no short anywhere else.

@oldturkey03 Я ищу ферритовую бусину 250 Ом. Но не знаю какая сила тока и частота.

@Алексей Гусев if you are looking for the one for an iMac, then the package size should be 0805. Something like a ILHB0805ER251V will work

@Алексей Гусев Если вы ищете для iMac, то размер корпуса должен быть 0805. Подойдет что-то вроде ILHB080805ER251V.
