Description
General part information
BLM21RK Series
The Murata BLM21RK series are EMIFIL chip ferrite beads for suppressing high frequency noise in digital interface 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. BLM21RK series ferrite beads can be used in a digital Interface. The resistance of these ferrite beads grows in lower frequency range therefore these are less effective for digital signal waveform at low frequency range.
