BLM02AX100SN1D

Chip Ferrite Bead Overview

The Murata BLM02AX100SN1D is a single-line ferrite chip bead designed for electromagnetic interference (EMI) suppression in compact surface-mount applications. It operates within an impedance range of 5 to 15 Ohms at a test frequency of 100 MHz, with a maximum DC resistance of 70 mOhms. The component supports a maximum DC current of 750 mA and functions reliably across a temperature range of -55°C to +125°C. Housed in a 1005 (0402 metric) package measuring 1.0 mm in length, 0.5 mm in width, and 0.5 mm in height, it provides effective noise filtering for high-density circuit designs.

Chip Ferrite Bead Procurement Notes

Verify the specific suffix configuration against official Murata documentation to ensure compatibility with required impedance tolerances and current ratings. Confirm RoHS compliance status and lead times directly with authorized distributors, as availability may vary by region. Ensure that the selected packaging format aligns with automated assembly requirements and storage conditions specified in the manufacturer's handling guidelines.

Chip Ferrite Bead Selection Notes

Select this component when designing for tight spatial constraints requiring a 0402 metric footprint. Evaluate the 750 mA current rating against peak load requirements to prevent performance degradation. Consider the 70 mOhm DC resistance impact on voltage drop in low-voltage supply rails. Validate that the 10 Ohm nominal impedance at 100 MHz matches the targeted noise frequency spectrum for effective filtering performance.
