BLM15HD182BH1D

Chip Ferrite Bead Overview

The Murata BLM15HD182BH1D is a surface-mount ferrite bead in the BLM15HD series, housed in a 0402 (1005 metric) package. It provides an impedance of 1800 Ω at 100 MHz and 2700 Ω at 1 GHz. The component has a maximum DC resistance of 2.2 Ω and a rated current of 200 mA. Operating temperatures range from -55°C to +125°C. Physical dimensions are 1 mm length, 0.5 mm width, and 0.5 mm height.

Chip Ferrite Bead Feature Summary

• High impedance characteristics for effective high-frequency noise suppression
• Compact 0402 surface mount footprint suitable for space-constrained designs
• Capable of handling rated DC currents while maintaining signal integrity

Chip Ferrite Bead Applications

• High-speed signal line filtering
• EMI suppression filter circuits

Chip Ferrite Bead Procurement Notes

Verify the specific suffix 'BH1D' against official Murata documentation to confirm terminal plating and packaging configuration. Ensure the selected variant matches the required impedance tolerance and current rating for the target application circuit. Cross-reference with authorized distributors to validate authenticity and traceability.

Chip Ferrite Bead Selection Notes

Select this component when high attenuation is required in minimal board space. The 200 mA rating limits suitability for power lines; verify that the operating current remains below this threshold to prevent saturation. Consider the 2.2 Ω DC resistance impact on voltage drop within the specific circuit design constraints.

Chip Ferrite Bead Part Context

This part belongs to the BLM15HD series of chip ferrite beads manufactured by Murata Electronics. The series is designed for EMI suppression in digital circuits. The 0402 package size allows for automated placement in dense PCB layouts. Ferrite materials convert high-frequency noise into heat.

Chip Ferrite Bead Replacement Considerations

Direct substitutes include other Murata 0402 ferrite beads with matching 1800 Ω @ 100 MHz impedance and 200 mA current ratings, such as those from the BLM15SN or BLM15AG series, provided physical dimensions and DC resistance specifications align with the original design requirements.
