The MI1206K900R-10 is a single-line ferrite bead manufactured by Laird-Signal Integrity Products, designed for surface-mount assembly in the 1206 (3216 metric) package. It exhibits an impedance of 90 Ohms at 100 MHz and supports a maximum rated current of 1.5A. The component features a maximum DC resistance of 80 milliohms and operates within a temperature range of -40°C to +125°C. Its physical dimensions are 3.20mm in length and 1.60mm in width, with a maximum height of 1.30mm.
Verify the RoHS compliance status carefully, as historical data indicates potential non-compliance for similar Laird part numbers ending in zero. Confirm the specific suffix '-10' denotes the correct environmental certification for your project requirements. Ensure the supplier provides official datasheets matching this exact manufacturer part number to avoid discrepancies in electrical parameters or packaging specifications.
Select this component when a 90 Ohm impedance at 100 MHz is required for 1206 footprint designs. It is suitable for circuits handling currents up to 1.5A where low DC resistance is critical. Consider the operating temperature range of -40°C to +125°C for environmental compatibility. Compare against alternatives like the MI1206N800R-00 if lower impedance is acceptable.
This component belongs to the MI series of high-current ferrite chip beads from Laird-Signal Integrity Products. The series is engineered for EMI filtering and RF inductor applications in compact surface-mount formats. The 1206 size offers a balance between current handling capability and board space efficiency for modern electronic assemblies.
Publicly confirmed direct substitutes include the Samsung Electro-Mechanics CIC31P601NE, which shares the 1206 package but differs in impedance and current rating. Verify functional equivalence before substitution.
