Procurement Notes

Verify the specific suffix designation during procurement, as variations such as A4 may indicate distinct packaging or testing configurations compared to standard listings. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer, as supply chain conditions for electronic components can fluctuate. Ensure the selected part number matches the exact electrical requirements and physical footprint needed for the target PCB layout.

Selection Notes

Select this component when multi-line EMI filtering is required within a constrained board area. The 1206 package offers a balance between current handling capability and size. Evaluate the 120 Ohm impedance profile against the target noise frequencies to ensure effective attenuation. Consider the 450 mA current rating to prevent saturation or excessive heating in the intended circuit application.

Part Context

This part belongs to the Fair-Rite 25 series of multilayer ferrite chip beads. These components utilize proprietary ferrite materials optimized for broadband noise absorption. The series is engineered for use in portable electronics and communication devices where space efficiency and reliable signal integrity are critical design constraints.
