BLM03HD102SN1D

Chip Ferrite Bead Overview

The Murata BLM03HD102SN1D is a single-line chip ferrite bead in the 0201 (0603 metric) surface-mount package. It provides an impedance of 1000 ohms at 100 MHz and 25% tolerance. The rated current is 120 mA with a maximum DC resistance of 2.9 ohms. Operating temperature ranges from -55°C to +125°C. Dimensions are 0.60mm length, 0.30mm width, and 0.33mm height.

Chip Ferrite Bead Feature Summary

• Designed for suppressing high-frequency noise in GHz frequency bands
• Multi-layer construction reduces resonance probability to ensure signal integrity
• Nickel barrier layer on external electrodes provides excellent soldering heat resistance
• Operates without requiring a stable ground connection

Chip Ferrite Bead Applications

• EMI suppression filters for portable devices
• Noise suppression for data lines
• Prevention of errors caused by local oscillator signals in mobile phones

Chip Ferrite Bead Procurement Notes

Verify the specific suffix SN1D against official Murata documentation to confirm packaging type and tape dimensions. Ensure the component meets RoHS and REACH compliance requirements for your target market. Confirm that the 120mA current rating aligns with your circuit design constraints before finalizing procurement.

Chip Ferrite Bead Selection Notes

Select this component when space is limited due to its compact 0201 footprint. Choose this part if the application requires significant attenuation at 100 MHz while maintaining low DC resistance. Verify that the 120mA current limit is sufficient for the signal line to prevent saturation or excessive heating during operation.

Chip Ferrite Bead Part Context

This component belongs to the BLM03H series of EMIFIL chip ferrite beads. The series is engineered for high-density mounting on printed circuit boards. It serves as a passive filter element within electronic circuits to mitigate electromagnetic interference.

Chip Ferrite Bead Replacement Considerations

Consult Murata's official cross-reference tools for verified substitutes. Ensure any replacement matches the 0201 package size, 1000 ohm impedance at 100 MHz, and 120 mA current rating.
