PE-0805FB102ST

Overview

The PE-0805FB102ST is a surface-mount ferrite chip bead from the FB series, designed for high-frequency noise suppression. It features an impedance of 1 kOhms at 100 MHz and a maximum DC current rating of 500 mA. The component has a maximum DC resistance of 400 mOhms and operates within a temperature range of -40°C to +105°C. Packaged in cut tape or reel formats, it utilizes SMD/SMT termination types.

Feature Summary

• Designed for electromagnetic interference suppression in electronic circuits
• Optimized for high-frequency noise attenuation on signal lines
• Compact 0805 surface-mount footprint for space-constrained designs

Applications

• High-speed signal line filtering under 1 GHz
• Power supply input/output decoupling
• General-purpose EMI suppression in compact electronics

Procurement Notes

Verify the specific packaging configuration (cut tape vs. reel) required for your assembly process, as availability may vary by distributor. Confirm that the 500 mA current rating aligns with your circuit's operational requirements to prevent saturation. Ensure the 1 kOhm impedance characteristic matches the target noise frequency spectrum for effective filtering performance.

Selection Notes

Select this component when a 1 kOhm impedance at 100 MHz is required for noise suppression. The 500 mA current rating suits moderate power applications. Compare against the PE-0402FB102ST if a smaller 0402 package is needed, noting its lower 300 mA current capacity. Ensure the operating temperature range of -40°C to +105°C meets environmental specifications.

Part Context

This part belongs to Pulse Electronics' FB series of ferrite chip beads. These components are engineered for suppressing electromagnetic interference in digital and analog circuits. The series offers various impedance values and current ratings in standard surface-mount packages to support diverse design constraints.

Replacement Considerations

The PE-0402FB102ST serves as a pin-compatible alternative in a smaller 0402 package, though it supports only 300 mA. Verify footprint compatibility and current derating before substitution.
