The Murata BLM15HB series are EMIFIL chip ferrite beads designed to suppress high-frequency noise in GHz band high-speed signal lines. These miniature, EIA 0402-sized ferrite beads effectively reduce resonance and noise without requiring ground connections, making them suitable for circuits lacking stable grounds. Featuring a nickel barrier structure for excellent solder heat resistance, they operate efficiently at frequencies of 1 GHz or higher. Common applications include EMI suppression in notebooks, digital still cameras, USB interfaces, mobile phones, and other portable electronic devices. They are available in a range of impedance values at 100 MHz and operate within a temperature range of -55°C to 125°C.
