BLM18BD182BH1D

Chip Ferrite Bead Overview

The Murata Electronics BLM18BD182BH1D is a single-line ferrite chip bead designed for surface-mount technology. It features a 0603 (1608 metric) package with dimensions of 1.6 mm in length and 0.8 mm in width. The component provides an impedance of 1800 ohms at a test frequency of 100 MHz, with a tolerance of 25%. It supports a maximum DC current of 150 mA and has a maximum DC resistance of 1.5 ohms. The device operates within a temperature range of -55°C to +125°C.

Chip Ferrite Bead Feature Summary

• Provides high impedance attenuation for electromagnetic interference suppression in compact surface-mount designs.

Chip Ferrite Bead Applications

• Power line filtering in electronic circuits
• Signal integrity management in data lines

Chip Ferrite Bead Procurement Notes

Verify the specific suffix BH1D against official Murata documentation to confirm packaging and tape-and-reel specifications. Ensure the selected variant matches the required impedance tolerance and current rating for the target application circuit. Cross-reference the RoHS compliance status directly with the manufacturer's latest datasheet to guarantee regulatory adherence for the intended market.

Chip Ferrite Bead Selection Notes

Select this component when a 0603 footprint is required for power line noise suppression. The 150 mA current rating suits low-power signal or control lines rather than high-current power rails. Consider the 1.5 ohm DC resistance impact on voltage drop if used in sensitive power delivery paths. Evaluate thermal performance within the specified -55°C to +125°C operating range.

Chip Ferrite Bead Part Context

This part belongs to the BLM18 series of ferrite beads from Murata Electronics. The series offers various impedance values and current ratings in standard SMD packages. The BLM18BD182BH1D specifically targets applications requiring moderate current handling with significant high-frequency noise attenuation in space-constrained layouts.

Chip Ferrite Bead Replacement Considerations

Public confirmed substitute part numbers are not available in the provided source material. Consult Murata's official cross-reference tools or distributor databases for verified alternatives that match the 0603 package, 1.8 kOhm impedance, and 150 mA current specifications.
