BLA31AG601SN4D

Chip Ferrite Bead Overview

The BLA31AG601SN4D is a ferrite chip bead array manufactured by Murata Electronics. It features an impedance of 600 Ohms with a tolerance of 25% at a test frequency of 100 MHz. The component supports a maximum DC current of 100 mA and has a maximum DC resistance of 350 mOhms. It is housed in a 1206 (3216 metric) surface mount package with dimensions of 3.2 mm length, 1.6 mm width, and 1.6 mm height. The operating temperature range spans from -55°C to +125°C.

Chip Ferrite Bead Feature Summary

• Provides differential mode noise filtering for signal lines
• Designed for surface mount assembly on printed circuit boards
• Constructed as a multi-channel ferrite chip bead array

Chip Ferrite Bead Applications

• High-speed data line noise suppression
• Signal integrity protection in digital circuits
• EMI reduction in compact electronic modules

Chip Ferrite Bead Procurement Notes

Verify the specific suffix SN4D against official Murata documentation to confirm packaging and tape specifications. Ensure the selected variant matches the required impedance tolerance and current rating for the target application. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and compliance with RoHS standards before finalizing procurement orders.

Chip Ferrite Bead Selection Notes

Select this component when a 1206 footprint is required for differential mode filtering. The 100 mA current rating suits low-power signal lines rather than power distribution paths. Compare the 350 mOhms DC resistance against system voltage drop requirements. Confirm that the 600 Ohm impedance at 100 MHz aligns with the noise frequencies present in the design environment.

Chip Ferrite Bead Part Context

This part belongs to the Murata EMIFIL BLA series of ferrite chip bead arrays. These components are engineered for suppressing electromagnetic interference in high-density electronics. The BLA series typically offers multiple channels within a single package to manage noise across parallel signal traces efficiently.
