BLM18BD102SN1D

Chip Ferrite Bead Overview

The Murata BLM18BD102SN1D is a single ferrite chip bead in a 0603 (1608 metric) surface-mount package. It provides an impedance of 1000 Ω at a test frequency of 100 MHz with a tolerance of ±25%. The component has a maximum DC resistance of 850 mΩ and a rated current of 100 mA. It operates within a temperature range of -55°C to +125°C.

Chip Ferrite Bead Feature Summary

• Provides high impedance for effective EMI suppression in signal lines
• Compact 0603 footprint suitable for space-constrained designs
• Capable of handling specified DC currents without saturation

Chip Ferrite Bead Applications

• High-speed signal line filtering
• EMI suppression filters
• Power supply noise reduction

Chip Ferrite Bead Procurement Notes

Verify the specific datasheet version and RoHS compliance status directly with Murata or authorized distributors before procurement. Confirm that the 100 mA current rating meets the application requirements, as exceeding this limit may cause performance degradation or thermal issues. Ensure the 0603 package dimensions align with the PCB layout constraints.

Chip Ferrite Bead Selection Notes

Select this component when a 1 kΩ impedance at 100 MHz is required for noise attenuation in compact circuits. The 100 mA current rating limits its use to low-current signal paths rather than high-power rails. Compare against other BLM18 series variants if higher current capacity or different impedance characteristics are needed for the specific circuit topology.

Chip Ferrite Bead Part Context

This part belongs to the Murata BLM18 series of ferrite beads, designed for general-purpose EMI suppression. The 'BD' suffix typically denotes specific material properties or packaging variations within the series. It is a standard passive component used widely in consumer electronics and industrial equipment for signal integrity management.

Chip Ferrite Bead Replacement Considerations

Check Murata's official substitution guide for equivalent parts within the BLM18 series. Verify that any substitute matches the 1000 Ω impedance at 100 MHz, 100 mA current rating, and 0603 package dimensions to ensure mechanical and electrical compatibility.
