I have a circuit board with a surface mounted inductor which I believe is a film inductor. The board is not working properly and there is a loud squealing sound coming from said inductor so I am trying to replace it. I have located it in the data sheet for the board but I am inexperienced at identifying and specifying inductors so I am having trouble identifying a suitable replacement or testing the inductor to confirm that it is indeed the malfunctioning component. Could anyone here advise on how to determine the specs of the inductor, how to make sure I find a replacement that is suitable, or how to test the current inductor to make sure it is actually the malfunctioning component? Advice on any of these topics would be much appreciated, pictures are below for reference.
The inductor says 2R2 135S as far as I can tell and the schematic has two annotations to the component: FDA1055-2R2M=P3 and IND-2D2UH-100-GP.
The only thing I have been able to find on my own is that the inductor must be 2.2 uH (That's what the 2R2 is, I think) but I'm not sure of any other specs.
