BLM18HK102SN1D

Chip Ferrite Bead Overview

The Murata BLM18HK102SN1D is a single-line ferrite chip bead in the EMIFIL BLM18H series, housed in an EIA 0603 (1608 metric) surface-mount package. It provides an impedance of 1000 ohms at a test frequency of 100 MHz with a tolerance of 25%. The component supports a maximum DC current of 50 mA and exhibits a maximum DC resistance of 1.5 ohms. It operates within a temperature range of -55°C to +125°C and features nickel barrier electrodes for soldering heat resistance.

Chip Ferrite Bead Feature Summary

• Designed for high-frequency noise suppression on general signal lines
• Nickel barrier electrode structure ensures excellent soldering heat resistance
• No grounding required, suitable for circuits without stable ground

Chip Ferrite Bead Applications

• High-speed signal line noise suppression
• EMI suppression filters
• Portable electronic devices

Chip Ferrite Bead Procurement Notes

Verify the specific suffix SN1D against the official Murata datasheet to confirm packaging details such as reel size or cut tape specifications. Ensure the selected variant matches the required impedance tolerance and current rating for the target application circuit design.

Chip Ferrite Bead Selection Notes

Select this component for low-current signal paths requiring moderate noise attenuation. The 50 mA current rating limits usage in power lines; verify that the operating current remains below this threshold to prevent saturation. The 0603 footprint offers a compact solution for space-constrained PCB layouts.

Chip Ferrite Bead Part Context

This part belongs to the Murata BLM18H series of multi-layer ferrite beads. These components are engineered to suppress electromagnetic interference in digital circuits. The series utilizes specialized ferrite materials to provide effective damping across a broad frequency spectrum while maintaining signal integrity.

Chip Ferrite Bead Replacement Considerations

Consult the official Murata cross-reference documentation for verified substitutes. Alternative parts must match the 0603 footprint, 1000 ohm impedance at 100 MHz, and compatible current handling capabilities.
