PE-0805PFBL221ST

Overview

The PE-0805PFBL221ST is a high-performance ferrite bead from Pulse Electronics, designed for surface-mount applications in the 0805 (2012 metric) package. It provides an impedance of 220 Ohms at 100 MHz with a maximum DC current rating of 1000 mA and a maximum DC resistance of 70 mOhm. The component operates within a temperature range of -40°C to +105°C and features a single power line configuration.

Feature Summary

• High-performance EMI suppression capability
• Surface-mount construction for automated assembly
• Power line signal filtering application

Applications

• EMI suppression on power lines
• Signal integrity protection in compact electronics
• High-frequency noise filtering in portable devices

Procurement Notes

Verify the specific suffix 'L' against official Pulse Electronics documentation to confirm it denotes the high-performance variant with 1000 mA rating. Ensure the ordering part number matches the required impedance and current specifications exactly. Cross-reference datasheets for thermal derating curves and mounting recommendations before finalizing procurement.

Selection Notes

Select this component when high current handling up to 1000 mA is required alongside significant impedance at 100 MHz. The low DC resistance minimizes voltage drop in power paths. Consider the 0805 footprint constraints and operating temperature range of -40°C to +105°C for compatibility with the target environment.

Part Context

This part belongs to the Pulse Electronics Ferrite Beads and Chips family. It is distinct from standard ferrite beads by its optimized material properties for higher current capacity while maintaining effective noise attenuation in RF and power circuits.

Replacement Considerations

Check for direct substitutes such as PE-0805PFB221ST if lower current ratings are acceptable. Verify that alternative components match the 220 Ohm impedance at 100 MHz and fit the 0805 package dimensions.
