BLM18BD182SH1D

Chip Ferrite Bead Overview

The Murata BLM18BD182SH1D is a single-line differential mode ferrite chip bead designed for surface mount technology. It features a 0603 (1608 metric) package with dimensions of 1.6 mm length, 0.8 mm width, and 0.6 mm height. The component provides an impedance of 1.8 kOhms at a test frequency of 100 MHz with a tolerance of 25%. It supports a maximum DC current of 0.05 A and has a maximum DC resistance of 40 Ohms. The operating temperature range spans from -55°C to +125°C.

Chip Ferrite Bead Feature Summary

• Provides effective electromagnetic interference suppression in high-frequency circuits through differential mode filtering characteristics.

Chip Ferrite Bead Applications

• High-speed data line protection
• Signal integrity management in compact electronic devices

Chip Ferrite Bead Procurement Notes

Verify the specific suffix 'H1D' against official Murata documentation to confirm packaging type and tape/reel specifications. Ensure the selected variant matches the required 0.05 A current rating for the target application circuit. Cross-reference the impedance value at 100 MHz with design requirements to prevent signal attenuation issues.

Chip Ferrite Bead Selection Notes

Select this component when space constraints require a 0603 footprint for EMI suppression on single lines. The low current rating of 0.05 A necessitates careful evaluation of the signal line's DC bias conditions. Verify that the 1.8 kOhm impedance profile aligns with the noise frequencies present in the specific system environment.
