Murata Ferrite Bead (Chip Bead), 1 x 0.5 x 0.5mm (0402 (1005M)), 220Ω impedance at 100 MHz

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

BLM15AX ferrite beads realise larger rated current and lower DC resistance than BLM15AG counterparts by utilising newly developed ferrite material. This range offers stable noise suppression performance, and has minimised performance change by stresses such as heat shock.
