The Murata BLM21PG series are EMIFIL chip ferrite beads for suppressing high frequency noise in power line application. These chip ferrite beads are designed for reducing the possibility of resonance to provide undistorted signal waveform. EMIFIL chip ferrite beads do not require connection to ground so they are effectively used in circuits without stable ground lines. The nickel barrier structure of the external electrodes provides excellent solder heat resistance. BLM21PG series can be used in high current circuits due to its low DC resistance and can match power lines to a maximum of 6A DC.
