LI0603B201R-10

Chip Ferrite Bead Overview

The LI0603B201R-10 is a single-line ferrite bead manufactured by Laird-Signal Integrity Products, designed for EMI suppression in compact circuits. It features an impedance of 200 Ohms at 100 MHz and supports a maximum DC current of 200 mA. The component has a maximum DC resistance (DCR) of 400 mOhms and operates within a temperature range of -40°C to +125°C. Housed in a standard 0603 (1608 Metric) surface-mount package with dimensions of 1.60mm x 0.80mm x 0.80mm, it is suitable for power and signal line filtering applications.

Chip Ferrite Bead Feature Summary

• Provides high-frequency noise suppression on power and signal lines
• Compact 0603 surface-mount footprint for space-constrained designs
• Single-line configuration for simple circuit integration

Chip Ferrite Bead Applications

• Power line filtering in portable electronics
• Signal line noise suppression in compact devices
• EMI mitigation in high-density PCB layouts

Chip Ferrite Bead Procurement Notes

Verify the specific electrical parameters against the official manufacturer datasheet before procurement, as ratings such as DC current and impedance are critical for circuit integrity. Confirm that the 0603 package dimensions align with your board layout constraints. Ensure compliance with RoHS3 standards if required by your manufacturing specifications. Cross-reference the part number with authorized distributors to confirm availability and authenticity.

Chip Ferrite Bead Selection Notes

Select this component when a low-current ferrite bead is required for EMI filtering in small form factors. The 200 mA rating limits its use to low-power signal or auxiliary power lines rather than main power rails. Consider the 400 mOhm DCR impact on voltage drop in sensitive circuits. Compare with higher current variants like the LI0603G series if load requirements exceed 200 mA.

Chip Ferrite Bead Part Context

This component belongs to the LI Series of ferrite beads from Laird-Signal Integrity Products, which offers various impedance and current ratings in the 0603 package. It serves as a passive filter element to attenuate high-frequency electromagnetic interference. The product is currently active and supported by official documentation including datasheets and CAD models for design integration.

Chip Ferrite Bead Replacement Considerations

Direct substitutes include other 0603 ferrite beads with similar 200 Ohm @ 100 MHz impedance and comparable current ratings. Verify that alternative components meet the same thermal and mechanical specifications. Check for pin-compatible options from other manufacturers if supply chain diversification is needed.
