BLM18PG331SN1D

Chip Ferrite Bead Overview

The Murata BLM18PG331SN1D is a single-line chip ferrite bead in the EMIFIL BLM18 series, housed in a 0603 (1608 metric) surface-mount package. It provides an impedance of 330 Ohms at 100 MHz with a maximum DC resistance of 150 mOhms and a rated current of 1.2A. The component operates within a temperature range of -55°C to +125°C and measures 1.60mm in length, 0.80mm in width, and 0.95mm in height.

Chip Ferrite Bead Feature Summary

• Provides high-impedance noise suppression for power lines in compact surface-mount designs
• Engineered for stable performance across wide industrial temperature ranges
• Low DC resistance minimizes voltage drop and power loss in direct current paths

Chip Ferrite Bead Applications

• Power supply line filtering
• EMI suppression circuits
• Noise reduction in portable electronic devices

Chip Ferrite Bead Procurement Notes

Verify the specific suffix SN1D against official Murata documentation to confirm packaging type and tape dimensions. Ensure the selected variant matches the required impedance tolerance and current rating for the target application circuit. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm authenticity and availability status before finalizing procurement orders.

Chip Ferrite Bead Selection Notes

Select this component when a 0603 footprint is required for power line noise attenuation. The 1.2A current rating suits moderate power applications where low insertion loss is critical. Compare the 330 Ohm impedance profile against SimSurfing data to ensure effective damping at the specific interference frequency of the design.

Chip Ferrite Bead Part Context

This part belongs to the Murata BLM18 series of EMIFIL chip ferrite beads. The series offers various impedance values and current ratings within the standard 0603 case size. The PG suffix typically indicates automotive-grade reliability standards, while SN1D specifies the specific termination and packaging configuration for automated assembly.

Chip Ferrite Bead Replacement Considerations

BLM18PG331SH1D shares identical electrical specifications but may differ in packaging or reel configuration.
