PE-01005FB121STA

Overview

The PE-01005FB121STA is a surface-mount ferrite bead from Pulse Electronics, designed for EMI suppression in signal lines. It features a 01005 (0402 metric) package with one line. The component provides an impedance of 120 Ohms at 100 MHz and has a maximum DC resistance of 600 milliohms. It supports a maximum current rating of 220 mA and operates within a temperature range of -40°C to +105°C.

Feature Summary

• Provides effective EMI/RFI noise suppression for high-frequency signal lines
• Utilizes multi-layer ferrite technology for compact miniature design
• Offers stable impedance characteristics across the specified frequency range

Applications

• Portable electronic devices requiring small form factor filtering
• Signal line protection in consumer electronics
• High-density circuit board designs with limited space

Procurement Notes

Verify the specific suffix 'STA' against official Pulse Electronics documentation to confirm packaging and compliance details. Note that some distributors list this part as obsolete; ensure availability through authorized channels or valid alternative sources before finalizing procurement plans.

Selection Notes

Select this component when a 01005 footprint is required for signal line filtering. Ensure the 220 mA current rating meets the application's peak load requirements. Verify that the 120 Ohm impedance at 100 MHz aligns with the target noise frequencies for effective suppression.

Part Context

This part belongs to the FB series of miniature ferrite beads from Pulse Electronics. These components are engineered for EMI suppression in tight spaces. The 01005 size represents one of the smallest available packages, suitable for advanced miniaturization trends in modern electronics manufacturing.

Replacement Considerations

Check for direct substitutes within the same series or compatible vendors. Confirm that any replacement matches the 01005 dimensions, 120 Ohm impedance, and 220 mA current rating to maintain circuit integrity.
