The BLM18K series chip Ferrite Bead 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. The BLM18K series can be used in high current circuits due to its low DC resistance. It can match power lines to a maximum of 6A DC and is suitable for general purposes.
-55 to 125°C Operating temperature range
Do not use products beyond the rated current as this may create excessive heat and deteriorate the insulation resistance.
