BLM15HG102SZ1D

Chip Ferrite Bead Overview

The Murata BLM15HG102SZ1D is a single-line chip ferrite bead in the EMIFIL BLM15H series, designed for high-frequency noise suppression. It features an impedance of 1000 ohms at 100 MHz and 1400 ohms at 1 GHz. The component has a maximum DC resistance of 1.1 ohms and a rated current of 250 mA. Housed in a compact 0402 (1005 metric) surface-mount package measuring 1.0 mm x 0.5 mm x 0.5 mm, it operates within a temperature range of -55°C to +125°C.

Chip Ferrite Bead Feature Summary

• Provides effective high-frequency noise suppression for GHz band applications
• Eliminates the need for circuit grounding due to its design
• Features nickel barrier layers on external electrodes for superior soldering heat resistance

Chip Ferrite Bead Applications

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

Chip Ferrite Bead Procurement Notes

Verify the suffix 'SZ1D' against official Murata documentation to confirm specific tape-and-reel or cut-tape packaging details, as datasheets often list 'SN1D'. Ensure the 1.1-ohm DCR and 250mA rating align with your circuit requirements. Confirm RoHS compliance status directly from the manufacturer's latest specification sheet before finalizing procurement orders.

Chip Ferrite Bead Selection Notes

Select this component for low-impedance signal lines requiring significant attenuation at 100 MHz. The 0402 footprint suits space-constrained designs. Verify that the 250mA current rating exceeds the maximum operating current of the target line to prevent saturation. Consider the 1.1-ohm DC resistance impact on signal integrity for sensitive power or data paths.
