The Murata BLM15BB series consists of EMIFIL chip ferrite beads designed to suppress high-frequency noise in high-speed signal lines. These miniature, EIA 0402 standard components effectively reduce resonance risks to maintain a clean, undistorted signal waveform. They do not require connection to ground, making them suitable for circuits without stable ground lines. The ferrite beads feature a nickel barrier on external electrodes for excellent solder heat resistance. Available in a variety of impedance values at 100 MHz, they are ideal for applications in industrial, power management, consumer electronics, and portable devices. Operating within a temperature range of -55°C to 125°C, they are effective at low impedance lines and miniaturized for space-constrained designs.
