BLA2AAG601SN4D

Chip Ferrite Bead Overview

The BLA2AAG601SN4D is a ferrite bead array manufactured by Murata Electronics, designed for signal line noise suppression. It features four independent channels within a single surface-mount package. The component exhibits an impedance of 600 Ohms at a test frequency of 100 MHz and supports a maximum DC current rating of 50 mA. Its maximum DC resistance (DCR) is specified at 1.1 Ohms. The device is housed in a compact 0804 (2010 metric) footprint with dimensions of 2.00 mm in length and 1.00 mm in width, reaching a maximum height of 0.60 mm. It operates reliably across a temperature range from -55°C to +125°C.

Chip Ferrite Bead Feature Summary

• Integrates four independent ferrite bead channels into a single compact surface-mount package for efficient multi-line filtering.
• Provides high impedance characteristics at 100 MHz to effectively attenuate high-frequency electromagnetic interference on signal lines.
• Constructed for robust performance across a wide industrial operating temperature range from -55°C to +125°C.

Chip Ferrite Bead Applications

• Noise suppression in high-speed digital signal transmission lines
• Electromagnetic interference filtering in portable electronic devices
• Signal integrity protection in automotive electronics systems

Chip Ferrite Bead Procurement Notes

Verify the specific ordering suffix SN4D to confirm the tape and reel packaging configuration required for automated assembly processes. Ensure that the selected variant matches the intended manufacturing workflow, as packaging options such as cut tape or Digi-Reel may differ based on the final character of the part number. Confirm RoHS compliance status through official manufacturer documentation prior to integration into regulated supply chains.

Chip Ferrite Bead Selection Notes

Select this component when designing circuits requiring simultaneous filtering for multiple signal lines within a constrained board area. The 0804 package offers a balance between current handling capability and footprint efficiency compared to smaller packages. Evaluate the 50 mA current rating against peak signal line currents to prevent saturation. Consider the 1.1 Ohm DC resistance impact on signal voltage levels for low-voltage logic interfaces.

Chip Ferrite Bead Part Context

This component belongs to the Murata EMIFIL BLA series, which specializes in chip ferrite bead arrays. These products are engineered to replace discrete components, reducing assembly complexity and PCB space consumption. The BLA series is widely utilized in consumer electronics and industrial applications where multi-channel EMI suppression is critical for maintaining signal integrity in dense circuit layouts.

Chip Ferrite Bead Replacement Considerations

BLA2ABB221SN4D: Offers lower impedance (220 Ohms) but shares the same 0804 package and 4-line configuration. BLA31BD601SN4D: Provides equivalent 600 Ohm impedance but utilizes a larger 1206 package with different physical dimensions.
