HI1812V101R-10

Chip Ferrite Bead Overview

The HI1812V101R-10 is a single-line ferrite chip bead from the Laird HI series, housed in an 1812 (4532 metric) surface-mount package. It provides an impedance of 100 ohms at 100 MHz and supports a maximum rated current of 8 A with a maximum DC resistance of 0.01 ohm. The component operates within a temperature range of -40°C to 125°C and has a maximum height of 0.01 inch.

Chip Ferrite Bead Feature Summary

• Provides efficient electromagnetic interference suppression for high-current applications
• Features low DC resistance to minimize power loss in signal and power lines
• Designed for compact surface-mount integration in dense circuit layouts

Chip Ferrite Bead Applications

• Power line filtering in portable electronics
• Signal line noise suppression in communication devices
• EMI mitigation in automotive electronic systems

Chip Ferrite Bead Procurement Notes

Verify the specific impedance tolerance and current derating curves against the official Laird datasheet before finalizing design integration. Confirm that the 1812 package dimensions align with the target PCB footprint and solder mask requirements. Ensure compliance with RoHS3 and REACH regulations as specified in the product documentation.

Chip Ferrite Bead Selection Notes

Select this component when high current handling up to 8 A is required alongside moderate EMI filtering. The 100-ohm impedance at 100 MHz targets common noise frequencies in digital circuits. Compare against the HI1812T800R-10 if higher impedance is needed, or the HI1206N101R-10 if space constraints require a smaller 1206 package.

Chip Ferrite Bead Part Context

This ferrite bead belongs to Laird's HI series, which focuses on high-current capabilities for signal integrity management. The 1812 package size balances current capacity with board space efficiency. It serves as a passive filter element to attenuate high-frequency noise without significantly affecting the desired signal path.

Chip Ferrite Bead Replacement Considerations

HI1812T800R-10 offers similar packaging but different impedance characteristics.
