BLM15HD102SN1D

Chip Ferrite Bead Overview

The Murata BLM15HD102SN1D is a multi-layer chip ferrite bead in the BLM15H series, designed for EMI suppression in GHz frequency bands. It features a 0402 (1005 metric) package with dimensions of 1.0 x 0.5 x 0.5 mm. The component provides an impedance of 1000 Ohms at 100 MHz and 2000 Ohms at 1 GHz, with a maximum DC resistance of 1.25 Ohms and a rated current of 250 mA. Operating within a temperature range of -55°C to +125°C, it utilizes a nickel barrier layer on external electrodes for soldering heat resistance.

Chip Ferrite Bead Feature Summary

• Designed to suppress high-frequency noise in GHz band high-speed signal lines
• Reduces resonance probability to ensure signal integrity without distortion
• Operates effectively in circuits lacking stable ground connections
• Nickel barrier layer on external electrodes provides excellent soldering heat resistance

Chip Ferrite Bead Applications

• EMI suppression filters for notebook PCs and digital still cameras
• Noise suppression for data transmission 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/reel specifications. Ensure the impedance tolerance matches the design requirement of ±25%. Confirm RoHS and REACH compliance status through the manufacturer's latest datasheet before finalizing procurement orders.

Chip Ferrite Bead Selection Notes

Select this component for low-impedance lines requiring compact EMI filtering in the GHz range. The 0402 size suits space-constrained designs. Verify that the 250 mA current rating meets the circuit's operational requirements. Consider the 1.25 Ohm DC resistance impact on signal voltage drop. Ensure compatibility with surface mount assembly processes given the small form factor.

Chip Ferrite Bead Part Context

This part belongs to the Murata BLM15H series of EMIFIL chip ferrite beads. The series is characterized by its ability to handle high-frequency noise suppression in small packages. The BLM15HD102SN1D specifically targets applications where standard ferrite beads may not provide sufficient impedance or physical footprint constraints exist.
