Toroidal Core

For EMI suppression on small conductors, Sintertech manufactures a complete line of extremely compact, high performance ferrite beads. They are often used on short, rigid or semi-rigid miniature conductors. They are uniquely suited for noise suppression on conductors carrying DC and AC, as well as digital or analog signals.

  • Internal dimensions from 4.6 mm to 15 mm
  • Precision finished smooth surfaces prevent damage to wire insulation
  • Extremely compact with small mass
  • Custom design available

  • Small diameter wires and conductors
  • Component leads of high gain/high bandwidth active device (e.g. Field effect or bipolar junction transistor)
