PE-0603PFB221ST

Overview

The PE-0603PFB221ST is a high-performance ferrite bead from Pulse Electronics, designed for surface-mount applications in the 0603 (1608 Metric) package. It features an impedance of 220 Ohms at standard test frequencies and supports a maximum current rating of 2.2 Amperes. The component exhibits a low DC resistance of 50 milliohms, ensuring minimal signal loss in power lines. It operates reliably within a temperature range of -40°C to 105°C and is RoHS compliant.

Feature Summary

• High current handling capability up to 2.2A for power line noise suppression
• Low DC resistance of 50mOhm to minimize voltage drop
• Compact 0603 surface-mount footprint for space-constrained designs

Applications

• Power supply output filtering
• High-speed data line EMI suppression
• Noise reduction in portable electronic devices

Procurement Notes

Verify the specific impedance frequency specification against the official datasheet, as ferrite characteristics vary by frequency. Confirm the operating temperature range meets your environmental requirements. Ensure the 0603 package dimensions align with your PCB layout constraints. Check for any recent lifecycle notifications or obsolescence warnings from Pulse Electronics before finalizing procurement plans.

Selection Notes

Select this component when high current capacity is required alongside effective high-frequency noise attenuation. The low DCR makes it suitable for sensitive power rails where voltage integrity is critical. Consider the thermal performance under continuous load conditions. Compare impedance profiles with alternative ferrites if specific frequency targeting is necessary for your EMI compliance strategy.

Part Context

This part belongs to Pulse Electronics' PFB series of ferrite beads, which are engineered for general-purpose EMI suppression. The series offers various impedance values and current ratings in standardized packages. The PE-0603PFB221ST specifically targets applications requiring robust noise filtering in compact form factors without compromising current carrying capacity.

Replacement Considerations

Consult official cross-reference lists for verified substitutes. Ensure replacement parts match the 220 Ohm impedance, 2.2A current rating, and 0603 package dimensions. Verify that alternative components meet the same RoHS and environmental standards.
