The Murata BLM15HB series are EMIFIL chip ferrite beads for suppressing high frequency noise in GHz band high speed signal line applications. 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. BLM15HB are suitable for noise suppression in 1GHz or higher frequency. Typical applications include EMI suppression for Note PC and DSC, noise suppression for data line, USB interface line and prevention of erroneous operation caused by local oscillation signal in mobile phones.
