BLM21SP601BH1D

Chip Ferrite Bead Overview

The Murata BLM21SP601BH1D is a single-channel ferrite chip bead in an 0805 (2012 metric) surface-mount package. It provides 600 Ohms impedance at 100 MHz with a 25% tolerance. The component supports a maximum DC current of 2.3 A and has a maximum DC resistance of 60 mOhms. It operates within a temperature range of -55°C to +150°C.

Chip Ferrite Bead Feature Summary

• Provides high-frequency noise suppression through ferrite material absorption
• Designed for surface-mount assembly on printed circuit boards
• Capable of handling significant direct current loads without saturation

Chip Ferrite Bead Applications

• Power supply line filtering
• EMI suppression circuits
• High-speed digital signal line protection

Chip Ferrite Bead Procurement Notes

Verify the specific suffix BH1D against official Murata documentation to confirm impedance, current rating, and termination specifications. Ensure the required operating temperature range aligns with the +150°C maximum limit. Confirm RoHS compliance status via the manufacturer's latest datasheet before integration into production designs.

Chip Ferrite Bead Selection Notes

Select this component when a 0805 footprint is constrained but higher current capacity than standard beads is required. The 2.3A rating distinguishes it from lower-current variants like the AG series. Verify that the 60mOhm DC resistance meets voltage drop requirements in the target power or signal path.

Chip Ferrite Bead Part Context

This part belongs to the BLM21SP series, which features enhanced current handling capabilities compared to standard BLM21AG components. The SP designation indicates a specialized formulation optimized for power integrity applications while maintaining effective high-frequency attenuation characteristics in compact packages.

Chip Ferrite Bead Replacement Considerations

Direct substitutes include BLM21SP331BH1D for lower impedance needs or BLM21BD601SN1D if lower current tolerance is acceptable. Verify physical dimensions and terminal compatibility before substitution.
