LI0603G121R-10

Chip Ferrite Bead Overview

The LI0603G121R-10 is a monolithic ferrite chip bead manufactured by Laird-Signal Integrity Products, designed for surface-mount assembly in the 0603 (1608 metric) package. It provides an impedance of 120 Ohms at a test frequency of 100 MHz. The component supports a maximum DC current rating of 1 A and exhibits a maximum DC resistance of 200 mOhms. It operates within a temperature range of -40°C to +125°C and complies with RoHS3 standards.

Chip Ferrite Bead Feature Summary

• Provides effective attenuation of high-frequency electromagnetic interference on power and signal lines
• Monolithic construction ensures mechanical stability and reliability in compact surface-mount layouts
• Low DC resistance minimizes voltage drop and power loss in direct current circuits

Chip Ferrite Bead Applications

• Power line filtering in portable electronic devices
• Signal integrity management in high-speed digital circuits
• EMI suppression in consumer electronics power supplies

Chip Ferrite Bead Procurement Notes

Verify the manufacturer designation as Laird-Signal Integrity Products when sourcing. Confirm the specific impedance value of 120 Ohms at 100 MHz matches design requirements. Ensure the 0603 package dimensions align with PCB footprint specifications. Check for RoHS3 compliance documentation if required by project regulations.

Chip Ferrite Bead Selection Notes

Select this component when a 120 Ohm impedance at 100 MHz is required for noise suppression. The 1 A current rating suits moderate power applications. The 200 mOhm DC resistance is suitable for low-loss signal paths. Consider the 0603 size constraint for space-limited designs.
