BLM18SP601SN1D

Chip Ferrite Bead Overview

The Murata BLM18SP601SN1D is a single-channel ferrite chip bead in the 0603 (1608 metric) surface-mount package. It provides an impedance of 600 Ohms at 100 MHz with a tolerance of ±25%. The component supports a maximum DC current of 1.5 A and has a maximum DC resistance of 168 mOhms. It operates within a temperature range of -55°C to +125°C. Physical dimensions are 1.6 mm length, 0.8 mm width, and 0.6 mm height.

Chip Ferrite Bead Feature Summary

• Provides high-impedance noise suppression for EMI/RFI attenuation in power lines
• Designed for surface-mount assembly on printed circuit boards
• Capable of handling high direct current loads without saturation

Chip Ferrite Bead Applications

• Power line filtering in electronic circuits
• EMI suppression for high-current signal paths
• Noise reduction in automotive electronics

Chip Ferrite Bead Procurement Notes

Verify the specific suffix SN1D against official Murata documentation to confirm packaging details and material composition. Ensure the selected variant matches the required 1.5 A current rating and 168 mOhm DC resistance specifications for the target application design.

Chip Ferrite Bead Selection Notes

Select this component when a 0603 footprint is required for high-current applications needing 600 Ohms impedance at 100 MHz. Compare the 1.5 A rating against the BLK18RK601SN1D if lower current is acceptable, or the BLK18AG601SN1D if different physical dimensions are permissible.

Chip Ferrite Bead Part Context

This part belongs to the Murata EMIFIL BLM18 series of ferrite beads. The series offers various impedance and current ratings within the standard 0603 package size. The SP suffix typically denotes specific electrical characteristics distinguishing it from other variants like AG or RK within the same family.

Chip Ferrite Bead Replacement Considerations

BLM18RK601SN1D offers similar impedance but lower current handling. BLM18AG601SN1D provides comparable performance with slight dimensional differences. Verify pin compatibility and thermal characteristics before substitution.
