HI1812T800R-10

Chip Ferrite Bead Overview

The HI1812T800R-10 is a monolithic ferrite chip bead from the Laird HI series, designed for high-current applications. It features an 80 Ohm impedance at 100 MHz and supports a maximum DC current of 6 A with a maximum DC resistance of 10 mOhms. The component utilizes a 1812 (4532 metric) surface-mount package measuring 4.50 mm in length, 3.20 mm in width, and up to 1.40 mm in height. It operates within a temperature range of -40°C to +125°C and complies with RoHS3 standards.

Chip Ferrite Bead Feature Summary

• Engineered for high-current power line filtering with low DC resistance to minimize power loss.
• Provides effective EMI mitigation and RF noise suppression in signal and power circuits.
• Constructed as a monolithic single-line device suitable for compact surface-mount layouts.

Chip Ferrite Bead Applications

• Data bus filtration
• Discrete component filtration in power supplies
• Telecom products

Chip Ferrite Bead Procurement Notes

Verify the manufacturer designation carefully, as some distributor listings may incorrectly identify Qnity as the manufacturer instead of Laird-Signal Integrity Products. Confirm the specific suffix indicates standard reel packaging. Ensure the requested quantity aligns with factory pack sizes, typically 2,500 units per reel, to avoid unnecessary cut-tape premiums or availability issues during procurement.

Chip Ferrite Bead Selection Notes

Select this component when circuit designs require handling continuous currents up to 6 A while maintaining low insertion loss via its 10 mOhm DC resistance. The 1812 footprint offers a balance between current capacity and board space. Verify that the 80 Ohm impedance at 100 MHz matches the target noise frequency spectrum for the specific power or signal line being filtered.

Chip Ferrite Bead Part Context

This part belongs to the Laird HI series of high-current ferrite chip beads. The series includes variants like HI1206N800R-00 and HI2220P701R-10, which differ in package size, current rating, and impedance values. The HI1812T800R-10 specifically targets mid-range high-current applications requiring robust EMI suppression in a standard 1812 SMD form factor.
