PE-1206FBA121ST

Overview

The PE-1206FBA121ST is a ferrite chip bead manufactured by Pulse Electronics, designed for surface-mount technology. It features a 1206 (3216 metric) array package with eight printed circuit board pads and four signal lines. The component provides an impedance of 120 Ohms at 100 MHz. It has a maximum DC resistance of 300 milliohms and a current rating of 350 mA. The operating temperature range spans from -40°C to +105°C.

Feature Summary

• Provides EMI suppression for multiple signal lines within a compact multi-layer ferrite structure
• Utilizes a four-line array configuration to manage noise in dense circuit layouts
• Designed for surface-mount assembly on standard PCB footprints

Applications

• Signal line filtering in electronic circuits
• EMI suppression in high-density data interfaces
• Noise reduction in portable electronic devices

Procurement Notes

Verify the specific datasheet version before integration, as manufacturing specifications may evolve. Confirm that the 1206 footprint matches the target PCB design exactly. Check RoHS compliance status against current regulatory requirements for the destination market. Ensure the 350 mA current rating meets the operational load of the intended signal lines without saturation.

Selection Notes

Select this component when four independent signal lines require simultaneous noise attenuation in a limited space. The 120 Ohm impedance at 100 MHz targets specific high-frequency interference profiles. Compare the 300 milliohm DC resistance against power loss constraints. Consider the 8-pad array layout for soldering reliability during automated placement processes.

Part Context

This part belongs to the FBA series of ferrite beads from Pulse Electronics. The series offers various impedance values tailored for different frequency suppression needs. The 1206 form factor allows for compact integration into modern electronics where space is constrained. Similar parts in the lineup include variants with different impedance ratings such as 30 Ohms or 300 Ohms.

Replacement Considerations

Direct substitutes include other 120 Ohm, 4-line ferrite beads in the 1206 array package. Verify pin compatibility and impedance curves match the original design requirements. Alternative manufacturers may offer similar performance but require re-validation of thermal and electrical characteristics.
