BLM15BB750SH1D

Chip Ferrite Bead Overview

The Murata BLM15BB750SH1D is a single ferrite chip bead in an SMD/SMT 0402 (1005 metric) package. It provides 75 Ohms impedance at a test frequency of 100 MHz with a 25% tolerance. The component supports a maximum DC current of 300 mA and has a maximum DC resistance of 400 mOhms. It operates within a temperature range of -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

• Designed for high-frequency noise suppression over a wide frequency range
• Single mode configuration for differential or single-ended signal lines
• Compact 0402 surface-mount footprint for space-constrained PCB layouts

Chip Ferrite Bead Applications

• High-speed digital signal line filtering
• Power supply noise suppression in compact electronics

Chip Ferrite Bead Procurement Notes

Verify the specific suffix 'H1D' against official Murata documentation to confirm tape-and-reel packaging specifications and moisture sensitivity level. Ensure the ordering part number matches the exact impedance and current ratings required for the target circuit design before finalizing procurement.

Chip Ferrite Bead Selection Notes

Select this component when a 0402 footprint is mandatory and 75 Ohms attenuation is required at 100 MHz. Confirm that the 300 mA current rating exceeds the peak operating current of the protected line. Verify thermal management requirements given the 400 mOhms DC resistance and 125°C maximum operating temperature limit.

Chip Ferrite Bead Part Context

This part belongs to the BLM15 series of ferrite beads from Murata Electronics. The series offers various impedance values and current ratings in the standard 0402 package size. The BLM15BB750SH1D specifically targets applications requiring moderate current handling with precise high-frequency noise characteristics.

Chip Ferrite Bead Replacement Considerations

Cross-reference with BLM15BB750SN1D for identical electrical parameters but potential packaging differences. Check BLM15BB750SZ1D if automotive infotainment qualification is required, noting its 200 mA rating differs from this part's 300 mA capacity.
