Procurement Notes

Verify the specific manufacturer part number against official Pulse Electronics documentation to ensure authenticity. Confirm that the shielding characteristics and impedance values match the design requirements. Check for RoHS compliance status as indicated in the official datasheet. Ensure the package dimensions align with the PCB footprint specifications before ordering.

Selection Notes

Select this component when space constraints require a 0402 footprint with high impedance characteristics. Consider the 300 mA current rating to ensure it meets the circuit's load requirements without saturation. The shielded design is suitable for applications requiring reduced EMI radiation. Verify the 100 MHz test frequency impedance matches the target noise spectrum.

Part Context

This component belongs to the ABSY series of shielded ferrite beads from Pulse Electronics. It is designed for surface-mount technology applications where size and performance are critical. The series offers various impedance options within the same physical footprint to accommodate different filtering needs.

Replacement Considerations

Cross-reference with other shielded 0402 ferrite beads offering similar 480 Ohm impedance at 100 MHz. Verify equivalent current ratings and DC resistance values. Ensure the replacement maintains the same thermal and mechanical specifications.
