The WE-CBF series from Wurth Elektronik are surface mount EMI suppression ferrite beads. These ferrite beads offer excellent anti EMI properties and low DC resistance. WE-CBF ferrite beads can be soldered directly on printed circuit board.
The Murata BLM18BA series are EMIFIL chip ferrite beads for suppressing high frequency noise in 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. BLM18BA series can minimize attenuation of the signal waveform due to its sharp impedance characteristics and various impedances are available to match signal frequency.
