# Correct designator L15 to FB1 ## Problem environment The ST Microelectronics reference designs specify a inductor when a ferrite bead is used. ## Steps to reproduce 1. Examine the coil nearest VDDA 1. Observe an inductor designator 1. Search for a inductance value ## Expected result A inductance value should accompany the inductor designator. ## Actual result The corresponding bill of materials specifies a ferrite bead. ## Workaround Ignore the inductor and replace with a ferrite bead with 600 Ohms resistance at 100 MHz cycle. ## Severity level This is **medium priority** because it could lead to power flaws at runtime.
