BLM18BD252SZ1D

Chip Ferrite Bead Overview

The Murata BLM18BD252SZ1D is a single-line chip ferrite bead in the EMIFIL BLM18 series, housed in a 0603 (1608 metric) surface-mount package. It provides an impedance of 2500 Ohms at a test frequency of 100 MHz with a tolerance of 25%. The component supports a maximum DC current of 150 mA and has a maximum DC resistance of 1.5 Ohms. It operates within a temperature range of -55°C to +125°C and measures 1.6 mm in length, 0.8 mm in width, and 0.95 mm in height.

Chip Ferrite Bead Feature Summary

• Designed to function as a resistor at noise frequencies to minimize resonance risks
• Single-line configuration for signal line filtering applications
• RoHS3 compliant construction

Chip Ferrite Bead Applications

• Signal line noise suppression
• Audio line noise filtering
• General EMI/RFI suppression in compact circuits

Chip Ferrite Bead Procurement Notes

Verify the suffix 'SZ1D' against official Murata documentation to confirm specific packaging or tape-and-reel specifications. Ensure the selected variant matches the required impedance tolerance and current rating for the target application circuit design.

Chip Ferrite Bead Selection Notes

Select this component when high impedance at 100 MHz is required for signal lines within a 0603 footprint. The 150 mA current rating limits suitability for power rails; it is intended for low-current signal paths where resonance reduction is critical.

Chip Ferrite Bead Part Context

This part belongs to the Murata EMIFIL BLM18 family of ferrite beads. The series is characterized by its ability to act resistively at noise frequencies, offering stable performance across the specified industrial temperature range while maintaining a small form factor suitable for dense PCB layouts.

Chip Ferrite Bead Replacement Considerations

BLM18BD252SN1D is a documented alternative within the same series featuring identical electrical characteristics but potentially different packaging suffixes.
