BLM ferrite beads from Murata are ideal for use in circuits with unstable ground lines as they do not require a ground connection. These ferrite beads are designed to function nearly as resistors at noise frequencies, 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_P ferrite beads can match power lines to a maximum of 6A dc. With low DC resistance, BLM_P variants are ideal for high current circuits. BLM15EG models also provide low DC resistance.

This series of ferrite beads are suitable for general use applications.
