PE-01005FB121ST

Overview

The PE-01005FB121ST is a miniature multilayer ferrite chip bead manufactured by Pulse Electronics. It features a 01005 (0402 metric) surface-mount package designed for high-density circuit applications. The component provides an impedance of 120 Ohms at 100 MHz with a maximum DC resistance of 530 milliohms. It supports a rated current of 240 mA and operates within a temperature range of -40°C to +105°C.

Feature Summary

• Utilizes advanced multilayer ferrite technology for effective EMI suppression in compact designs.
• Provides signal line filtering with specified impedance characteristics at 100 MHz.
• Features a shielded SMD/SMT construction suitable for automated assembly processes.

Applications

• EMI suppression in portable electronic devices
• Signal line filtering in high-density PCB layouts
• Noise reduction in consumer electronics

Procurement Notes

Verify the specific ordering suffix and packaging configuration, as distribution channels may list variations such as tape-and-reel quantities. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer before placing orders. Ensure the part number matches the exact impedance and current ratings required for your design specifications.

Selection Notes

Select this component when space constraints require a 01005 footprint for ferrite beads. Ensure the application current does not exceed 240 mA to maintain performance. Verify that the 120 Ohm impedance at 100 MHz aligns with the target noise frequencies. Consider the 530 milliohm DCR impact on signal integrity and power loss in the circuit path.

Part Context

This part belongs to Pulse Electronics' FB series of miniature ferrite beads. The series utilizes multilayer technology to achieve high impedance in small packages. The 01005 size represents one of the smallest form factors available for surface-mount ferrite components, targeting ultra-compact mobile and wearable electronics markets.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-referencing requires matching impedance, current rating, and package dimensions with other manufacturers' 01005 ferrite beads. Verify electrical parameters and thermal characteristics before substituting.
