BLM15BX182SN1D

Chip Ferrite Bead Overview

The Murata BLM15BX182SN1D is a single-line ferrite chip bead in the EMIFIL BLM15 series, housed in a 0402 (1005 metric) surface-mount package. It provides an impedance of 1800 Ohms at a test frequency of 100 MHz with a tolerance of ±25%. The component supports a maximum DC current of 250 mA and exhibits a maximum DC resistance of 900 mOhms. It operates within a temperature range of -55°C to +125°C.

Chip Ferrite Bead Feature Summary

• Provides high-impedance noise suppression for signal lines in compact designs
• Engineered for stable performance across wide industrial temperature ranges
• Supports standard surface-mount reflow soldering processes

Chip Ferrite Bead Applications

• High-speed signal line filtering
• EMI suppression filters
• Noise reduction in portable electronic devices

Chip Ferrite Bead Procurement Notes

Verify the specific suffix SN1D against the official Murata datasheet to confirm impedance and current ratings. Ensure the ordering code matches the required 0402 package dimensions. Confirm RoHS compliance status through the manufacturer's documentation before finalizing procurement specifications.

Chip Ferrite Bead Selection Notes

Select this component when a 0402 footprint is required for space-constrained layouts. Choose based on the 250 mA current rating and 1800 Ohm impedance target at 100 MHz. Compare against the BLM15BD variant if lower current handling or different DC resistance characteristics are acceptable for the circuit design.

Chip Ferrite Bead Part Context

This part belongs to the Murata BLM15 series of ferrite beads, designed for general-purpose noise suppression. The series offers various impedance values and current ratings in standardized metric packages. The BLM15BX variant specifically targets applications requiring higher current capacity compared to other series members.

Chip Ferrite Bead Replacement Considerations

BLM15BD182SN1D: Lower current rating (100 mA), higher DC resistance (1.4 Ohms). BLM15HD182SN1D: Higher current rating (200 mA), higher DC resistance (2.2 Ohms).
