BLM03BB100SN1D

Chip Ferrite Bead Overview

The Murata BLM03BB100SN1D is a single-line ferrite chip bead in the EMIFIL BLM03 series, housed in a compact 0201 (0603 metric) surface-mount package measuring 0.6 mm x 0.3 mm x 0.3 mm. It provides an impedance of 10 Ohms at a test frequency of 100 MHz with a tolerance of ±25%. The component supports a maximum DC current of 300 mA and features a maximum DC resistance of 400 mOhms. It operates within a temperature range of -55°C to +125°C.

Chip Ferrite Bead Feature Summary

• Provides electromagnetic interference suppression for single signal lines through high-frequency impedance characteristics.
• Designed for space-constrained applications utilizing a standard 0201 surface-mount footprint.
• Capable of handling continuous direct current loads up to 300 mA without saturation.

Chip Ferrite Bead Applications

• Noise filtering on high-speed digital signal lines
• Power supply line decoupling in portable devices
• EMI suppression in automotive electronic control units

Chip Ferrite Bead Procurement Notes

Verify the specific suffix against official Murata documentation to confirm material composition and performance curves. Ensure the ordering part number matches the required impedance tolerance and current rating. Confirm RoHS compliance status and moisture sensitivity level requirements prior to procurement to align with assembly process specifications.

Chip Ferrite Bead Selection Notes

Select this component when a low-impedance path is required for DC power while attenuating noise around 100 MHz. The 0201 package suits dense PCB layouts. Evaluate the 300 mA current limit against peak load requirements to prevent thermal failure. Compare against higher impedance variants if broader frequency attenuation is necessary.

Chip Ferrite Bead Part Context

This component belongs to the Murata EMIFIL BLM03 series of ferrite beads. The series offers various impedance values and current ratings within the same 0201 form factor. The BLM03BB100SN1D specifically targets applications requiring moderate noise suppression with relatively high current capacity in minimal board space.

Chip Ferrite Bead Replacement Considerations

Cross-reference with other BLM03 series parts such as BLM03AX100SN1D or BLM03BB100SZ1D. Verify that substitute components match the 10 Ohm impedance at 100 MHz, 300 mA current rating, and 0201 package dimensions before implementation.
