Procurement Notes

Verify the specific current rating requirement, as sources cite both 200 mA and 400 mA. Confirm the package dimensions match the 3.2x1.6x2mm specification. Ensure the supplier provides official datasheets confirming AEC-Q200 qualification and RoHS compliance before procurement.

Selection Notes

Select this component for applications requiring compact common mode filtering in space-constrained designs. The 3216 footprint suits dense PCB layouts. Verify thermal management capabilities given the operating temperature range up to 125°C and the specific DC resistance value for power loss calculations.

Part Context

This part belongs to the Bourns SRF3216 series of chip inductors. These components are engineered for general-purpose filtering and EMI suppression in portable and automotive electronics. The series utilizes ferrite materials to achieve high impedance characteristics in a small form factor.

Replacement Considerations

Consult manufacturer cross-reference lists for verified substitutes. Ensure replacement parts maintain identical impedance at 100 MHz, DCR limits, and physical dimensions for direct board compatibility.
