BLM18KN102EH1D

Chip Ferrite Bead Overview

The Murata BLM18KN102EH1D is an automotive-grade ferrite chip bead in a 0603 (1608 metric) SMD package. It provides 1 kOhms impedance at 100 MHz with a 25% tolerance. The component supports a maximum DC current of 740 mA and has a maximum DC resistance of 200 mOhms. It operates within a temperature range of -55°C to +175°C and holds AEC-Q200 qualification.

Chip Ferrite Bead Feature Summary

• Designed for noise suppression in power lines
• Functions nearly as a resistor at noise frequencies to reduce resonance possibility
• Qualified for high-temperature automotive applications up to +175°C

Chip Ferrite Bead Applications

• Noise suppression in automotive power lines
• High-temperature electronic circuit filtering

Chip Ferrite Bead Procurement Notes

Verify the specific suffix EH1D against official Murata documentation to confirm the 175°C rating and 740 mA current handling. Ensure the order matches the 0603 package dimensions and 1 kOhm impedance specifications required for the target application.

Chip Ferrite Bead Selection Notes

Select this component when high-temperature stability up to 175°C is required for power line noise suppression. The 740 mA current rating suits moderate power applications, while the 1 kOhm impedance targets specific frequency attenuation needs in compact 0603 footprints.

Chip Ferrite Bead Part Context

This part belongs to the Murata EMIFIL BLM18KN series, specialized for automotive use. It differs from standard BLM18HD parts by offering extended temperature ranges and higher current capabilities suitable for harsh automotive environments.

Chip Ferrite Bead Replacement Considerations

Check for other BLM18KN variants with matching 1 kOhm impedance and 740 mA ratings. Verify that any substitute maintains the AEC-Q200 qualification and 175°C operating limit.
