The Murata BLM18BD series are EMIFIL chip ferrite beads designed to suppress high-frequency noise in high-speed signal lines. These compact, EIA 0603 standard ceramic components effectively reduce resonance and distortion without requiring connection to ground, making them suitable for circuits with unstable ground lines. The nickel barrier structure on the external electrodes ensures excellent solder heat resistance. Available in various impedance values at 100MHz, these ferrite beads feature sharp impedance characteristics that minimize signal attenuation across a wide operating temperature range from -55°C to 125°C. They are ideal for use in industrial, power management, consumer electronics, and portable device applications.
