BLM ferrite beads from Murata are ideal for use in circuits with unstable ground lines as they do not require a ground connection. At noise frequencies, these ferrite beads are designed to function nearly as a resistor, leaving signal wave forms undistorted and reducing the possibility of resonance. Excellent solder heat resistance is provided by the nickel barrier construction of the external electrodes.

BLM_A ferrite beads are effective in noise suppression ranging from 30 MHz to several hundred MHz, and generate impedance from relatively low frequencies.

BLM series ferrite beads are suitable for general use applications.
