Procurement Notes

Verify RoHS compliance status and specific packaging options such as cut tape or reel configurations directly with authorized distributors. Confirm that the ordering suffix matches the required termination style and ensure the component meets the intended operating temperature range specifications before finalizing procurement orders.

Selection Notes

Select this component when space constraints require a 0402 footprint and the application demands 1 kOhm impedance at 100 MHz. Ensure the circuit current does not exceed 300 mA to prevent saturation. Verify compatibility with SMD/SMT assembly processes and confirm thermal stability requirements fall within the -40°C to +105°C operational window.

Part Context

This part belongs to the FB series of ferrite chip beads manufactured by Pulse Electronics. It is specifically engineered for compact electronics where minimal board space is available. The product utilizes advanced multi-layer construction to achieve high performance in small packages, distinguishing it from traditional single-layer ferrite beads.

Replacement Considerations

Consult official manufacturer substitution guides for equivalent parts with matching impedance curves and current ratings. Verify pinout compatibility and physical dimensions before replacing to ensure seamless integration into existing PCB layouts without redesign.
