The Murata BLM18EG series are EMIFIL chip ferrite beads designed for high-frequency noise suppression in the GHz band for general signal line applications. These miniaturized, EIA 0603 standard components effectively reduce resonance and prevent signal waveform distortion. They do not require ground connections and feature a nickel barrier structure on external electrodes for excellent soldering heat resistance. The modified internal electrode structure minimizes stray capacitance, extending the effective frequency range. They offer low impedance at 100 MHz, low DC resistance, high rated current, and excellent DC characteristics. Operating within a temperature range of -55°C to 125°C, these ferrite beads are suitable for compact, low-profile electronic devices across industrial, power management, consumer electronics, and portable device applications.
