LF0805A252R-10

Chip Ferrite Bead Overview

The LF0805A252R-10 is a single-line ferrite bead from the Laird-Signal Integrity Products 0805 series, designed for power and signal line filtering. It exhibits an impedance of 1.248 kOhms at 100 MHz with a maximum DC resistance of 1.25 Ohms. The component supports a rated current of 100mA and operates within a temperature range of -40°C to 125°C. Housed in a standard 0805 (2012 Metric) surface-mount package measuring 2.00mm x 1.25mm x 0.90mm, it is supplied in tape and reel formats.

Chip Ferrite Bead Feature Summary

• Provides high impedance attenuation for electromagnetic interference suppression on sensitive signal and power traces.

Chip Ferrite Bead Applications

• Power supply input filtering
• High-speed digital signal line noise reduction

Chip Ferrite Bead Procurement Notes

Verify RoHS3 compliance status and lead times directly with authorized distributors or the manufacturer. Confirm that the specific order suffix matches the required packaging format. Ensure the procurement channel is authorized to guarantee component authenticity and traceability for critical electronic assemblies.

Chip Ferrite Bead Selection Notes

Select this component when high-frequency noise suppression is required on low-current lines. The 100mA rating limits suitability for high-power applications. Verify that the 1.25 Ohm DC resistance does not introduce unacceptable voltage drop in the target circuit design compared to lower-resistance alternatives.

Chip Ferrite Bead Part Context

This ferrite bead belongs to the Laird 0805 series of EMI filtering components. These devices are engineered to suppress high-frequency noise in compact surface-mount layouts. The series offers various impedance values to match specific frequency requirements while maintaining a standardized footprint for automated assembly processes.

Chip Ferrite Bead Replacement Considerations

Direct substitutes include other 0805 ferrite beads with similar 1.2k Ohm impedance at 100 MHz and compatible current ratings. Verify pin compatibility and thermal characteristics before substitution.
