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.

Also it can be used up to 150 ℃.

BLM21SP series can be used in high current circuits

due to its low DC resistance.
