Murata Icon X Features

1.The chip ferrite beads BLM series is designed to
  function nearly as a resistor at noise frequencies,
  which greatly reduces the possibility of resonance and
  leaves signal wave forms undistorted.
  BLM series is effective in circuits without stable
  ground lines because BLM series does not need a
  connection to ground.
2.The nickel barrier structure of the external
  electrodes provides excellent solder heat resistance.
3.BLM31KN series can be used in high current circuits
  due to its low DC resistance. It can match power lines
  to a maximum of 6A DC.
  Extended the spec of  former BLM31PG/41PG series.
  Got larger rated current at same impedance value of
  BLM31PG/41PG series.
