Overview

The Murata BLM18SG700TN1D is a high-performance ferrite bead engineered for effective EMI suppression in single power lines. Its primary function is to attenuate unwanted high-frequency noise while allowing DC and low-frequency signals to pass with minimal impedance. A critical design consideration when selecting ferrite beads is the trade-off between impedance at the target frequency and DC resistance; the BLM18SG700TN1D offers a substantial 70 Ohms at 100 MHz with a low 20mOhm DC resistance, minimizing power loss and voltage drop in sensitive circuits.

Key Features

Impedance: 70 Ohms @ 100 MHz
Max Current Rating: 4A
Max DC Resistance: 20mOhm
Operating Temperature: -55°C to 125°C
Package: 0603 (1608 Metric)
Dimensions: 1.60mm x 0.80mm x 0.65mm

Applications

The component is engineered for deployment in systems requiring high reliability and performance under specific operating conditions. It provides functional stability across the stated design envelope.

Power sequencing for high-speed digital interfaces (e.g., DDR memory buses)
EMI filtering in compact DC-DC converter outputs
Noise suppression for sensor signal conditioning circuits
Decoupling of sensitive analog front-end components
