TOROIDAL CHOKE CORES (GTC)

Toroidal Choke Core are manufactured with iron-based amorphous metal ribbon. They are unique combination of ultra-high induction, high saturation induction, high energy storage capability and low core loss for high frequency magnetic components which are significantly smaller than conventional components.

Applications

  • DC Output inductors
  • Power factor correction chokes
  • Differential mode input chokes
  • Flyback Transformer

Benefits

  • Linear Permeability for wide range of frequency
  • Small sizes
  • High saturation flux density (1.56T)
  • Low temperature rise due to low loss
  • Low loss-owing to thin amorphous ribbon
