BLM18PG330SN1D

Chip Ferrite Bead Overview

The Murata BLM18PG330SN1D is a single-line chip ferrite bead in the EMIFIL BLM18P series, designed for high-current power line noise suppression. It features a 0603 (1608 metric) surface-mount package with dimensions of 1.6mm length, 0.8mm width, and 0.8mm height. The component provides an impedance of 33 Ω at 100 MHz and supports a maximum DC current of 3A. Its maximum DC resistance is 25 mΩ, ensuring low insertion loss in power circuits. It operates within a temperature range of -55°C to +125°C and complies with RoHS and REACH standards.

Chip Ferrite Bead Feature Summary

• Engineered for suppressing high-frequency electromagnetic interference in power supply lines
• Capable of handling high direct current loads up to 3A without saturation
• Constructed from specialized ferrite material optimized for broadband noise absorption

Chip Ferrite Bead Applications

• Power supply input filtering
• EMI suppression filters
• Noise reduction in digital circuit power rails

Chip Ferrite Bead Procurement Notes

Verify the complete part number including suffix SN1D to ensure correct packaging and specifications. Confirm RoHS compliance status if required by specific regulatory frameworks. Check datasheet for moisture sensitivity level and reflow soldering profile recommendations to prevent component damage during assembly processes.

Chip Ferrite Bead Selection Notes

Select this component when a 0603 footprint is constrained but high current capacity is required. The 3A rating distinguishes it from standard signal-line ferrites. Ensure the target noise frequency aligns with the 33 Ω impedance peak at 100 MHz. Verify that the 25 mΩ DC resistance meets the voltage drop requirements of the specific power rail design.

Chip Ferrite Bead Part Context

This component belongs to the Murata BLM18P series, which specializes in high-current applications compared to the standard BLM18KG or BLM18PG series. The 'P' designation indicates enhanced current handling capabilities suitable for power distribution networks. It serves as a passive filter element within the broader EMIFIL product family.
