The Murata BLM21AG series chip ferrite bead is designed to function nearly as a resistor at noise frequencies, which greatly reduces the possibility of resonance and leaves signal wave forms undistorted. It is effective in circuits without stable ground lines. It can be used in high current circuits due to its low DC resistance.
Nickel barrier structure of the external electrodes provides excellent solder heat resistance
Operating temperature range from -55 °C to 125 °C
Does not need a connection to ground
