Part Number: TRF371109EVM

Hi 

I am designing my new RF system and using TRF371109EVM (slwu069b) as a reference to draw my schematic. I find there are lots of ferrite chip beads used at some power rails, such as FB1/2/3/4. 

They are only labeled as 120. Although I know this value refers to the impedance value of the ferrite beads, the impedance of the them is strongly related to the frequency of use. Therefore, it is not enough to guide us to select the appropriate device. Can anyone help double check the part number of these FB used in this EVM board? Is the BOM of this EVM available? 

Regards
