BLM03HD102FN1D

Chip Ferrite Bead Overview

The Murata BLM03HD102FN1D is a single-channel ferrite chip bead in the BLM series, housed in an SMD/SMT 0201 (0603 metric) package with dimensions of 0.6 mm length, 0.3 mm width, and 0.3 mm height. It provides an impedance of 1 kOhms at a test frequency of 100 MHz with a tolerance of 25%. The component supports a maximum DC current of 135 mA and has a maximum DC resistance of 2.4 Ohms. It operates within a temperature range of -55°C to +125°C.

Chip Ferrite Bead Feature Summary

• Provides high-impedance noise suppression for signal lines using ferrite material properties.
• Designed for surface-mount assembly in compact electronic circuits.
• Engineered to maintain performance across a wide industrial temperature range.

Chip Ferrite Bead Applications

• EMI suppression filters
• High-speed signal line protection

Chip Ferrite Bead Procurement Notes

Verify the specific suffix FN1D against official Murata documentation to confirm packaging and tape-and-reel specifications. Ensure the selected variant matches the required impedance tolerance and current rating for the target circuit design before finalizing procurement orders.

Chip Ferrite Bead Selection Notes

Select this component when space-constrained designs require a 0201 footprint ferrite bead. The 1 kOhm impedance at 100 MHz suits general EMI filtering. Verify that the 135 mA current rating exceeds the circuit's peak operating current to prevent saturation or excessive heating during normal operation.

Chip Ferrite Bead Part Context

This part belongs to the Murata BLM series of power ferrite beads. These components are widely used in consumer electronics and industrial equipment for suppressing electromagnetic interference on data and power lines without significantly affecting the desired signal integrity.
