Toroid

Toroid

Toroids provide a convenient and very effective shape for many applications (wide band, pulse, power, and inductor). The continuous magnetic path yields the highest effective permeability and lowest flux leakage of any shape.

  1. Material (-X): prefix for NiZn (ie. M-665) or suffix for MnZn (ie. T-665-M20)
  2. Thickness: may be adjusted to suit application
  3. Tolerances (dimensional): ±2% (nominal value may vary based on material choice)
  4. Tolerance (magnetic): Inductance ±20% (grading available)
  5. Finishing: edge rounding and parylene (or other) coating available
TOROIDS:
SMALL (OD < 0.512)
