BLM18HG102SN1D

Chip Ferrite Bead Overview

The Murata BLM18HG102SN1D is a single-line ferrite chip bead in a 0603 (1608 metric) surface-mount package. It provides an impedance of 1 kOhms at 100 MHz with a tolerance of ±25%. The component has a maximum DC resistance of 1.6 Ohms and a rated current of 100 mA. Physical dimensions are 1.6 mm in length, 0.8 mm in width, and 0.95 mm in height. It operates within a temperature range of -55°C to +125°C.

Chip Ferrite Bead Feature Summary

• Monolithic ferrite construction for effective high-frequency noise suppression
• Compact 0603 surface-mount footprint suitable for space-constrained designs
• Single-line configuration for simple circuit integration

Chip Ferrite Bead Applications

• High-speed signal line filtering
• EMI suppression filters
• Audio line noise reduction

Chip Ferrite Bead Procurement Notes

Verify the specific suffix SN1D against official Murata documentation to confirm packaging type and tape specifications. Ensure the selected distributor sources from authorized channels to guarantee component authenticity and traceability. Confirm RoHS compliance status matches current regulatory requirements before finalizing procurement orders.

Chip Ferrite Bead Selection Notes

Select this component when a 1 kOhm impedance at 100 MHz is required for noise attenuation. The 100 mA current rating limits suitability to low-current signal lines rather than power rails. The 0603 package size must be compatible with the target PCB land pattern and assembly capabilities.

Chip Ferrite Bead Part Context

This part belongs to the Murata EMIFIL BLM18H series of ferrite beads. The series offers various impedance values and current ratings within the standard 0603 package format. These components are designed primarily for suppressing electromagnetic interference in digital and analog circuits.

Chip Ferrite Bead Replacement Considerations

Cross-reference with other BLM18HG variants or equivalent 0603 ferrite beads from other manufacturers if supply constraints exist. Verify that substitute parts match the 1 kOhm impedance, 100 mA rating, and physical dimensions to ensure board compatibility.
