BLM02KX180SN1D

Chip Ferrite Bead Overview

The Murata BLM02KX180SN1D is a single-line ferrite chip bead in a 01005 (0402 metric) surface-mount package. It provides an impedance of 18 ohms at a test frequency of 100 MHz with a tolerance of 25%. The component supports a maximum DC current of 1.2 A and has a maximum DC resistance of 45 mOhms. It operates within a temperature range of -55°C to +125°C, with physical dimensions of 0.4 mm length, 0.2 mm width, and 0.2 mm height.

Chip Ferrite Bead Feature Summary

• Provides targeted attenuation for high-frequency noise on power lines through specific impedance characteristics.

Chip Ferrite Bead Applications

• Power line filtering applications

Chip Ferrite Bead Procurement Notes

Verify the exact suffix SN1D against the manufacturer's latest datasheet to confirm packaging and material specifications. Ensure the 01005 footprint matches the target PCB design constraints. Confirm RoHS3 compliance status if required by specific regional regulations or end-product standards before finalizing procurement.

Chip Ferrite Bead Selection Notes

Select this component when space-constrained designs require EMI suppression in the smallest available passive footprint. The 1.2 A current rating makes it suitable for low-to-medium power signal or power rails where minimal DC resistance is critical. Verify that the 18-ohm impedance profile aligns with the specific noise frequencies present in the circuit environment.

Chip Ferrite Bead Part Context

This part belongs to the BLM02K series, which represents Murata's ultra-miniature ferrite beads designed for dense modern electronics. The 01005 case size allows for placement in compact mobile devices and advanced consumer electronics where board real estate is severely limited compared to standard 0402 or larger packages.

Chip Ferrite Bead Replacement Considerations

Direct substitutes must match the 01005 footprint, 18 Ohm impedance at 100 MHz, and 1.2 A current rating. Verify equivalent DC resistance and temperature stability from other manufacturers offering similar miniature ferrite solutions.
