The Murata BLM18BB series are EMIFIL chip ferrite beads designed to suppress high-frequency noise in high-speed signal lines. These miniature EMI filters help prevent resonance, ensuring undistorted signal waveforms. Notably, they do not require grounding connections, making them suitable for circuits lacking a stable ground. Their nickel barrier external electrodes provide excellent solder heat resistance. Available in various impedance values at 100MHz, they feature sharp impedance characteristics that minimize signal attenuation. These ferrite beads comply with the EIA 0603 standard, operate within a temperature range of -55°C to 125°C, and are ideal for use in industrial, power management, consumer electronics, and portable device applications.
