PE-1206FBA301ST

Overview

The PE-1206FBA301ST is a four-channel ferrite bead array manufactured by Pulse Electronics, designed for electromagnetic interference (EMI) suppression in surface-mount applications. It operates within a temperature range of -40°C to 105°C and features a 1206 (3216 metric) package with an eight-pad configuration. The component provides an impedance of 300 Ohms at 100 MHz, supports a maximum current rating of 250 mA, and exhibits a maximum DC resistance of 400 milliohms.

Feature Summary

• Multi-line EMI suppression capability integrated into a single compact footprint
• High-temperature stability suitable for demanding operational environments
• Low DC resistance design to minimize signal loss and power dissipation

Applications

• High-speed data line filtering in portable electronic devices
• Signal integrity protection in consumer electronics interfaces
• Common-mode noise reduction in multi-conductor cable assemblies

Procurement Notes

Verify the specific revision status as this part number is listed as obsolete or discontinued in official distributor records. Confirm availability through authorized channels or qualified alternative sources if immediate procurement is required. Ensure that any substitute components maintain identical electrical characteristics and physical dimensions to guarantee compatibility with existing PCB layouts and assembly processes.

Selection Notes

Select this component when designing circuits requiring simultaneous filtering of multiple signal lines within a constrained board area. The four-channel architecture simplifies layout compared to discrete beads. Consider the 250 mA current rating and 400 mOhm DCR to ensure adequate performance for low-power digital signals without excessive voltage drop or thermal issues during normal operation.

Part Context

This component belongs to the FBA series of ferrite multi-layer beads from Pulse Electronics. These parts are engineered specifically for high-frequency noise attenuation in dense electronic assemblies. The 1206 form factor allows for automated surface-mount placement, supporting efficient manufacturing workflows while delivering reliable EMI performance across various industrial and commercial applications.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, engineers should consult manufacturer engineering change notices or contact Pulse Electronics directly for validated replacement recommendations that meet the original specifications.
