BLM02BX151SN1D

Chip Ferrite Bead Overview

The Murata BLM02BX151SN1D is a single-line ferrite bead chip designed for signal line noise suppression. It features an impedance of 150 Ohms at 100 MHz and supports a maximum DC current of 280 mA. The component has a maximum DC resistance (DCR) of 700 milliohms. It utilizes a 01005 (0402 metric) surface-mount package with dimensions of 0.40 mm length, 0.20 mm width, and a maximum height of 0.22 mm. The device operates within a temperature range of -55°C to +125°C.

Chip Ferrite Bead Feature Summary

• Provides high-impedance noise attenuation for high-frequency signals in compact layouts
• Supports low-current signal lines with minimal DC voltage drop due to low resistance
• Engineered for reliability across wide industrial temperature ranges

Chip Ferrite Bead Applications

• Noise filtering on high-speed digital signal lines
• EMI suppression in portable electronic devices
• Signal integrity protection in compact consumer electronics

Chip Ferrite Bead Procurement Notes

Verify the specific suffix SN1D against the manufacturer's official datasheet to confirm packaging type and tape/reel specifications. Ensure the selected variant matches the required impedance tolerance and current rating for the target circuit design before finalizing procurement orders.

Chip Ferrite Bead Selection Notes

Select this component when space constraints require a 01005 footprint for signal line filtering. Confirm that the 280 mA current rating exceeds the maximum operating current of the protected line to prevent saturation. Validate that the 150 Ohm impedance at 100 MHz aligns with the noise frequency spectrum requiring suppression.

Chip Ferrite Bead Part Context

This part belongs to the Murata EMIFIL BLM02 series, which focuses on miniaturized ferrite beads for modern surface-mount applications. The series offers various impedance values within the 01005 package size to address diverse EMI/RFI mitigation needs in densely populated printed circuit boards.
