Ferrite Toroids

Small parts, Superior Performance

The excess energy created by circuits inside your consumer electronics or communication system can lead to significant EMI infiltration—and Laird’s ferrite toroids are designed to filter this interference efficiently and as unobtrusively as possible.  The cylindrical shape and magnetic power of our unique ferrite material work together to uniformly distribute the excess energy so you can properly manage the voltage of a current and separate signals of different frequencies—this keeps your product running smoothly and optimized for best performance.

Benefits of Our Ferrite Toroids

Constructed from ultra-thin mixtures of iron, nickel and zinc oxides, our ferrite toroids are characterized by their impressively small, lightweight size that provide superb EMI reduction while remaining open to normal circuit operation.  We offer a variety of sizes and shapes that can be custom-designed to fit your specific application needs.  Other benefits include:

  • Superior size and weight for optimization of applications and frequency levels
  • No coupling with adjacent components
  • Resistive core coatings of Parylene and Epoxy at a 0.0005mm thickness but others available upon request
  • The lowest cost of Ohms of impedance
  • AEC-Q200 compliance
