BLM18EG221TH1D

Chip Ferrite Bead Overview

The Murata BLM18EG221TH1D is a single ferrite chip bead in a 0603 (1608 metric) surface-mount package. It provides an impedance of 220 Ohms at a test frequency of 100 MHz with a tolerance of 25%. The component supports a maximum DC current of 1 A and exhibits a maximum DC resistance of 150 mOhms. It operates within a temperature range of -55°C to +125°C and measures 1.6 mm in length, 0.8 mm in width, and 0.8 mm in height.

Chip Ferrite Bead Feature Summary

• Designed for noise suppression in driver circuits due to low DC resistance and high rated current capacity.
• Features excellent direct current characteristics suitable for power line filtering applications.

Chip Ferrite Bead Applications

• Noise suppression of driver circuits
• General EMI suppression filters

Chip Ferrite Bead Procurement Notes

Verify the specific suffix 'TH1D' against official Murata documentation to confirm tape and reel packaging specifications. Ensure the selected variant matches the required impedance tolerance and current rating for the target application circuit design.

Chip Ferrite Bead Selection Notes

Select this component when a 0603 footprint is required for high-current noise suppression. The 1 A rating distinguishes it from lower-current variants in the same series. Verify that the 220 Ohm impedance profile aligns with the target noise frequency spectrum.
