BLM18DN601SH1D

Chip Ferrite Bead Overview

The Murata BLM18DN601SH1D is a surface-mount ferrite chip bead designed for high-current applications. It operates within the EMIFIL BLM18DN series and features a 0603 (1608 metric) package with dimensions of 1.6 mm length, 0.8 mm width, and 0.95 mm maximum height. The component provides an impedance of 600 Ohms at a test frequency of 100 MHz with a tolerance of 25%. It supports a maximum DC current rating of 700 mA and maintains a maximum DC resistance of 0.85 Ohms. The device functions reliably across a temperature range of -55°C to +125°C and holds AEC-Q200 qualification.

Chip Ferrite Bead Procurement Notes

Verify that the specific suffix matches the required current rating and impedance tolerance. Confirm AEC-Q200 compliance if automotive application is intended. Check datasheet for moisture sensitivity level and reflow soldering profile requirements. Ensure packaging format aligns with production equipment capabilities.

Chip Ferrite Bead Selection Notes

Select this component when high current handling is required alongside standard 0603 footprint constraints. Compare against lower current variants like BLM18HD or higher current options like BLM18SP based on specific circuit load requirements. Verify impedance characteristics match the noise spectrum of the target application.
