LI0603E151R-00

Chip Ferrite Bead Overview

The LI0603E151R-00 is a single-line ferrite bead from the Laird-Signal Integrity Products LI Series, designed for EMI filtering in power and signal lines. It features a 0603 (1608 metric) surface-mount package with dimensions of 1.60mm x 0.80mm x 0.80mm maximum height. The component provides an impedance of 150 Ohms at 100 MHz, supports a rated current of 500mA, and has a maximum DC resistance of 250 milliohms. It operates within a temperature range of -40°C to 125°C.

Chip Ferrite Bead Feature Summary

• Provides high impedance attenuation for electromagnetic interference suppression on single power or signal traces
• Utilizes a compact 0603 surface-mount footprint for dense PCB layout integration
• Engineered for stable performance across industrial temperature ranges

Chip Ferrite Bead Applications

• Power line filtering in portable electronic devices
• Signal integrity protection in high-speed digital circuits
• EMI suppression in automotive electronics modules

Chip Ferrite Bead Procurement Notes

Verify component status carefully as this specific suffix may indicate obsolete or end-of-life status compared to active variants like the R-10 suffix. Confirm availability through official manufacturer channels or authorized distributors. Ensure the selected part matches the required impedance and current ratings for your specific circuit design before procurement.

Chip Ferrite Bead Selection Notes

Select this component when a 150 Ohm impedance at 100 MHz is required for a single-line application. Ensure the PCB layout accommodates the 0603 package size and that the operating current does not exceed the 500mA rating. Consider thermal management requirements given the 250 milliohm DC resistance under load conditions.

Chip Ferrite Bead Part Context

This ferrite bead belongs to the LI Series from Laird-Signal Integrity Products, which offers various impedance values and current ratings in standard chip packages. The series is widely used for broadband noise suppression in consumer, industrial, and automotive applications requiring reliable EMI control without significant signal degradation.

Chip Ferrite Bead Replacement Considerations

Public documentation indicates the LI0603E151R-00 is obsolete. Verify if the LI0603E151R-10 serves as a direct functional substitute with identical electrical parameters. Consult manufacturer substitution guides for confirmed equivalents.
