BLM31AJ601SH1L

Chip Ferrite Bead Overview

The Murata BLM31AJ601SH1L is a single-line ferrite chip bead in a 1206 (3216 metric) surface-mount package. It provides an impedance of 600 Ohms at a test frequency of 100 MHz with a tolerance of ±25%. The component supports a maximum DC current of 200 mA and has 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-frequency noise suppression through ferrite material absorption
• Designed for surface-mount integration on printed circuit boards
• Monolithic construction ensures structural stability

Chip Ferrite Bead Applications

• High-speed data line filtering
• Power supply noise attenuation
• General-purpose EMI suppression in compact electronics

Chip Ferrite Bead Procurement Notes

Verify the specific suffix SH1L against official Murata documentation to confirm packaging and tape-and-reel specifications. Ensure the selected variant matches the required impedance tolerance and current rating for the target application circuit design.

Chip Ferrite Bead Selection Notes

Select this component when a 1206 footprint is required for space-constrained designs. The 200 mA current rating limits suitability for high-power lines, making it appropriate for signal or low-current power rails requiring significant high-frequency attenuation.

Chip Ferrite Bead Part Context

This part belongs to the BLM31 series, which utilizes Murata's proprietary monolithic ferrite technology. The series offers various impedance values and current ratings within standardized EIA sizes, allowing designers to balance noise performance with physical board space requirements effectively.

Chip Ferrite Bead Replacement Considerations

Cross-reference with BLM31AJ601SN1L for potential packaging differences. Verify that any substitute maintains the 600 Ohm impedance at 100 MHz and meets the 200 mA current handling capability.
