Toroidal solutions bring higher efficiency!  
• Lower EMI Emission!  
• Zero Noise!  
• Smaller volume and lighter weight!  
• Lower cost

Material use efficiency:  
Toroidal magnetic core, use for winding coil 100% area (LIMB). It improves all inductors and transformers properties; magnetic, electrical, thermal, mechanical, and of course reliability and the lower cost because there is no Yoke!

Leakage flux :  
Toroidal core has generally no leakage flux, therefore no additional noise sources from leakage flux, and no EMI in electronic systems.

DM Noise pollution:  
DM Noise from Toroidal solution is much smaller than the Classic EI or C core solutions

Thermal issues:  
Thermal field inThermal field in toroidal magnetic core is uniform. It improves cooling efficiency.toroidal magnetic core is uniform. It improves cooling efficiency.

Insulation failure rate:  
In toroidal component only one place can be dangerous for insulations it’s between the first and last turns of the winding. It simplifies, reduces the cost of insulations and improve reliability!
