A T20 toroidal ring ferrite core is a magnetic component commonly used in inductors, transformers, and EMI filters. Its toroidal (doughnut) shape provides efficient magnetic flux containment, minimizing electromagnetic interference (EMI) and enhancing performance in various electronic circuits.

Key Specifications:

• Dimensions:

  • Outer Diameter (A): 20.0 mm
  • Inner Diameter (B): 10.0 mm
  • Height (C): 12.0 mm

• Material: Typically made from Mn-Zn ferrite materials, offering high permeability and low core losses.

• Inductance Factor (A_L): Varies based on material; for instance, a T20 core made from HS10 material has an A_L value of approximately 10,000 nH.

Applications:

• Transformers: Utilized in power and signal transformers to maintain winding integrity and insulation.
• Inductors: Employed in various inductor designs, including power inductors and filter inductors, to ensure consistent inductance values.
• EMI Filters: Integral in components requiring precise inductance and minimal electromagnetic interference.
