BLM15HD102BH1D

Chip Ferrite Bead Overview

The Murata BLM15HD102BH1D is a single-type chip ferrite bead in the EMIFIL BLM15HD series, housed in an EIA 0402 (1005 metric) surface-mount package with dimensions of 1.0 mm length, 0.5 mm width, and 0.5 mm height. It provides an impedance of 1000 Ohms at 100 MHz with a tolerance of ±25%, rising to 2000 Ohms at 1 GHz. The component supports a maximum DC current of 250 mA and exhibits a maximum DC resistance of 1.8 Ohms. It operates within a temperature range of -55°C to +125°C.

Chip Ferrite Bead Feature Summary

• Designed for high-frequency noise suppression in GHz band applications
• Multi-layer construction reduces resonance probability to prevent signal distortion
• Nickel barrier layer on external electrodes ensures excellent soldering heat resistance
• Operates effectively without requiring a stable ground connection

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
• High-speed signal line filtering in portable devices

Chip Ferrite Bead Procurement Notes

Verify the suffix 'BH1D' against official Murata documentation to confirm specific termination and packaging details, as variations exist within the BLM15HD family. Ensure the selected part matches the required 0402 footprint and electrical ratings for the target circuit design before finalizing procurement orders.

Chip Ferrite Bead Selection Notes

Select this component for low-impedance lines requiring significant attenuation at 100 MHz and above. The 0402 size suits dense PCB layouts, while the 250 mA rating limits usage in high-current power paths. Confirm compatibility with peak reflow temperatures due to the nickel barrier electrode structure.

Chip Ferrite Bead Part Context

This part belongs to the Murata EMIFIL BLM15HD series, which specializes in suppressing high-frequency noise in compact electronic devices. The series utilizes multi-layer ferrite technology to provide effective filtering in small form factors suitable for modern consumer electronics and portable equipment.

Chip Ferrite Bead Replacement Considerations

BLM15HD102SN1D offers identical electrical characteristics but may differ in reel packaging or tape specifications. Verify that any substitute maintains the same 0402 dimensions and impedance profile to ensure mechanical and functional compatibility.
