BLM18AG102SH1D

Chip Ferrite Bead Overview

The Murata BLM18AG102SH1D is a single-line ferrite chip bead in an EIA 0603 (1608 metric) 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 450 mA and has a maximum DC resistance of 500 mOhms. It operates within a temperature range of -55°C to +125°C.

Chip Ferrite Bead Feature Summary

• Designed for high-frequency noise suppression in general signal lines without requiring a ground connection.
• Features a nickel barrier structure on external electrodes to ensure excellent soldering heat resistance.
• Multi-layer construction reduces the possibility of resonance to provide undistorted signal waveforms.

Chip Ferrite Bead Applications

• Electromagnetic interference suppression in portable devices
• Noise filtering for power management circuits
• Signal line protection in consumer electronics

Chip Ferrite Bead Procurement Notes

Verify the specific suffix against official Murata documentation, as ordering codes may indicate variations in packaging or tape-and-reel specifications. Confirm RoHS compliance status and automotive qualification requirements if applicable to your design. Ensure the selected variant matches the required impedance tolerance and current rating for the target application circuit.

Chip Ferrite Bead Selection Notes

Select this component for applications requiring compact noise suppression in low-impedance lines. The 0603 footprint suits space-constrained designs. Evaluate the 450 mA current rating against peak load conditions to prevent saturation. Consider the 1000 Ohm impedance profile for effective attenuation in the 30 MHz to several hundred MHz range.

Chip Ferrite Bead Part Context

This part belongs to the EMIFIL BLM18A series of multi-layer ferrite beads manufactured by Murata Electronics. The series is engineered for suppressing electromagnetic interference in digital and analog circuits. The BLM18AG variant specifically targets general-purpose applications with standardized impedance characteristics suitable for broad-spectrum noise reduction.

Chip Ferrite Bead Replacement Considerations

Direct substitutes include BLM18AG102SN1D and BLM18AG102SH1D variants from Murata, which share identical electrical parameters but may differ in reel packaging quantities. Cross-reference impedance curves to ensure compatibility with specific frequency noise profiles.
