The TUB4/2/5-3B1 is an EMI-Suppression Tube can be used in solenoid coils with almost the same effect as rods. The inner hole is often used to insert wires to make a ferrite coil former. In EMI suppression applications tube can also be shifted over wires. Because the magnetic flux path is then closed, a steep increase in impedance results. In such cases however the sensitivity for DC currents is rather high.
  • For general EMI suppression
  • With wires inserted used as ferrite coil former
