BLM15BD102SN1D

Chip Ferrite Bead Overview

The Murata BLM15BD102SN1D is a single-line chip ferrite bead in the EMIFIL BLM15 series, housed in an EIA 0402 (1005 metric) surface-mount package measuring 1.0mm x 0.5mm x 0.5mm. It provides an impedance of 1000 Ohms at 100 MHz with a tolerance of 25%. The component supports a maximum DC current of 250 mA and exhibits a maximum DC resistance of 1.25 Ohms. It operates within a temperature range of -55°C to +125°C.

Chip Ferrite Bead Feature Summary

• Designed for high-frequency noise suppression in GHz band applications
• Eliminates the need for circuit grounding due to single-line configuration
• Nickel barrier layer on external electrodes ensures superior soldering heat resistance

Chip Ferrite Bead Applications

• EMI suppression filters for notebook PCs and digital still cameras
• Noise suppression for data transmission lines
• Prevention of errors caused by local oscillator signals in mobile phones

Chip Ferrite Bead Procurement Notes

Verify the specific suffix against official Murata documentation to confirm exact impedance tolerances and packaging configurations. Ensure the procurement source provides valid RoHS compliance declarations consistent with the manufacturer's current standards. Cross-reference the part number with authorized distributor catalogs to validate authenticity and traceability before finalizing orders.

Chip Ferrite Bead Selection Notes

Select this component for low-impedance signal lines requiring compact noise filtering in portable devices. The 0402 footprint suits space-constrained designs where standard grounding is unavailable. Evaluate the 250 mA current rating against peak load requirements to prevent saturation. Confirm compatibility with reflow soldering profiles given the nickel barrier electrode construction.

Chip Ferrite Bead Part Context

This component belongs to the Murata EMIFIL BLM15HD/BLM15BD family of multi-layer ferrite beads. These parts are engineered specifically for suppressing electromagnetic interference in high-speed digital circuits. The series utilizes specialized ferrite materials optimized for attenuation characteristics above 100 MHz, distinguishing them from general-purpose inductors.
