The BLM15AG102SN1D is a high speed chip type surface mount EMI filter beads, chips and arrays manufactured by Murata consisting of a chip type ferrite bead of 1K ohm with high frequency characteristics. The material composition of the EMI filter bead is of a ceramic base with Ni-Zn ferrite core material, and an epoxy resin on top for mounting purposes. The filter bead is compact with a 1608 size package, and the rated current range for the device is from 1.0A to 4.0A (RMS). This EMI filter is designed for superior signal integrity, providing greater common mode and differential-mode noise suppression for a wide range of applications that require high frequency stability, such as high speed communication systems. The high frequency characteristics are based on the Ni-Zn ferrite core material, which has excellent characteristics, and is equivalent to a filter bead with an impedance value of 1000 ohm at 100MHz.
