BLM18KG700TZ1D

Chip Ferrite Bead Overview

The Murata BLM18KG700TZ1D is a single-line ferrite bead in a 0603 (1608 metric) surface-mount package. It provides an impedance of 70 Ohms at 100 MHz with a maximum DC resistance of 22 milliohms. The component supports a rated current of 3.5 Amperes and operates within a temperature range of -55°C to +125°C. Certified to AEC-Q200 standards, it measures 1.60mm x 0.80mm x 0.95mm.

Chip Ferrite Bead Feature Summary

• Provides high-current noise suppression for power lines
• Features low DC resistance to minimize power loss
• Automotive-grade reliability certified under AEC-Q200

Chip Ferrite Bead Applications

• DC power line filtering for automotive electronics
• EMI suppression in compact mobile equipment
• Noise reduction in portable navigation devices

Chip Ferrite Bead Procurement Notes

Verify the suffix TZ1D confirms the specific tape-and-reel packaging format required for automated assembly processes. Confirm that the AEC-Q200 qualification aligns with target automotive application requirements. Ensure the 3.5A current rating meets circuit load specifications without saturation. Check RoHS3 compliance status for environmental regulatory adherence.

Chip Ferrite Bead Selection Notes

Select this component when a 0603 footprint is constrained but higher current handling than standard beads is needed. The 70 Ohm impedance targets specific frequency noise profiles. Compare against lower impedance variants if voltage drop is critical. Verify thermal management capabilities within the -55°C to +125°C operational envelope for the intended environment.

Chip Ferrite Bead Part Context

This part belongs to the BLM18KG series, designed as a high-current power ferrite bead. It offers improved current handling compared to conventional 0603 beads, managing up to twice the typical rated current while maintaining a small form factor. The series aims to replace larger 0805 or 1206 components in space-constrained designs.

Chip Ferrite Bead Replacement Considerations

BLM18KG700TN1D shares identical electrical characteristics including 70 Ohm impedance and 3.5A rating. Verify package compatibility and lead configuration differences between TN1D and TZ1D suffixes before substitution.
