GB International designs and manufactures custom toroidal transformers and inductors for a variety of power supply and power conversion applications.  A toroidal transformer or inductor is a component that is designed on a doughnut shaped core. Toroidal components offer small size, less leakage inductance and lower electromagnetic interference (EMI).
 
Where are toroidal transformers and inductors found? 
 
   • Switch mode power supplies.
   • Filter applications. 
   • Electromagnetic Interference (EMI) sensitive circuits.      
 
Design upper limits of a toroidal transformer or inductor:
 
1. Typical minimum requirements to be specified for a toroidal component design are:
 
   • No load inductance in uH
   • Full load inductance in uH
   • DC Current in Amperes
   • AC Current in Amperes peak to peak
   • Operating frequency is needed for core calculations and wire sizing
 
2. Core material is selected for the known operating frequency or frequencies.
3. Other Toroidal component design considerations are space limitations and mounting technique.
4. Lead terminations are also specified through the design of a toroidal component.

A toroidal component design may vary widely in terms of power rating, inductance, voltage level (low to high), operating frequency, size, impedance, bandwidth (frequency response), packaging, winding capacitance, and other parameters.
