PE-0805AFB102ST

Overview

The PE-0805AFB102ST is a ferrite bead manufactured by Pulse Electronics, designed for EMI suppression in high-speed signal lines. It features an impedance of 1000 Ohms at 100 MHz and operates within a temperature range of -40°C to +105°C. The component utilizes a surface-mount 0805 (2012 metric) package with dimensions of 2.00mm x 1.25mm. It supports a maximum DC current of 500 mA and has a maximum DC resistance of 400 mOhms. This multi-layer chip bead is RoHS compliant and suitable for applications requiring effective noise filtering.

Feature Summary

• Provides high impedance for effective electromagnetic interference suppression
• Designed specifically for high-speed signal line protection
• Utilizes a compact surface-mount footprint for space-constrained designs

Applications

• High-speed digital signal line filtering
• EMI suppression in portable electronic devices
• Noise reduction in communication equipment

Procurement Notes

Verify the specific datasheet version as this part may be subject to discontinuation notices. Confirm availability through authorized distributors, as stock levels fluctuate. Ensure compliance with RoHS3 standards if required by your manufacturing process. Check for any tariff implications when importing into specific regions. Validate that the 0805 package size matches your PCB layout constraints before finalizing procurement.

Selection Notes

Select this component when high attenuation is required for signals up to 1 GHz. The 1000 Ohm impedance makes it suitable for suppressing broadband noise. Consider the 500 mA current rating to ensure it does not saturate under normal operating conditions. The 0805 package offers a balance between performance and board space. Compare against lower impedance variants if less aggressive filtering is sufficient for the application.

Part Context

This component belongs to Pulse Electronics' ferrite bead family, often associated with the Larson brand technology. It is part of the FB series, which includes various impedance values and package sizes. Similar parts include the PE-0805FB102ST and PE-0805PFB121ST, offering different impedance characteristics or power line filtering capabilities within the same form factor.
