The chip ferrite beads BLM series is designed to function nearly as a resistor at noise frequencies,which greatly reduces the possibility of resonance and leaves signal wave forms undistorted. BLM series is effective in circuits without stable ground lines because BLM series does not need a connection to ground. The nickel barrier structure of the external electrodes provides excellent solder heat resistance.BLM21SP series can be used in high current circuits due to its low DC resistance.
