BLA2ABD102SN4D

Chip Ferrite Bead Overview

The BLA2ABD102SN4D is a four-line ferrite bead array manufactured by Murata Electronics, designed for EMI suppression in signal lines. It features an impedance of 1000 Ohms at 100 MHz with a tolerance of 25%. The component supports a maximum DC current of 50 mA and has a maximum DC resistance of 1.8 Ohms. It operates within a temperature range of -55°C to +125°C. The device utilizes a surface-mount 0804 (2010 metric) package with dimensions of 2.0 mm length, 1.0 mm width, and 0.6 mm height.

Chip Ferrite Bead Feature Summary

• Provides effective electromagnetic interference suppression for high-speed signal lines through integrated ferrite bead arrays.
• Utilizes a compact surface-mount footprint suitable for dense circuit board layouts.
• Ensures stable noise filtering performance across a wide industrial operating temperature range.

Chip Ferrite Bead Applications

• Signal line filtering in compact electronic assemblies
• EMI suppression for data transmission circuits
• Noise reduction in portable digital devices

Chip Ferrite Bead Procurement Notes

Verify the specific suffix codes against official Murata documentation to confirm exact impedance and packaging specifications. Ensure compatibility with standard reflow soldering profiles for surface-mount assembly. Confirm RoHS compliance status if required by project regulations. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and availability.

Chip Ferrite Bead Selection Notes

Select this component when high impedance attenuation is required for multiple signal lines within a restricted board area. The 0804 package offers a balance between current handling capacity and spatial efficiency. Consider the 50 mA current rating to ensure the component does not saturate under normal operating conditions. Verify that the 1000 Ohm impedance value aligns with the target noise frequency spectrum.

Chip Ferrite Bead Part Context

This component belongs to the BLA series of SMD block type EMI suppression filters from Murata Electronics. These arrays are engineered to replace discrete ferrite beads, reducing component count and assembly time. The BLA2ABD variant specifically denotes a four-line configuration optimized for differential or multi-signal applications requiring uniform noise characteristics across all channels.
