Large-Size Ferrite Cores

More volume for higher performance

 Intro Pic

 

With the new large-size ferrite cores, TDK offers an opportunity for higher power. Large-size cores also allow for optimizing magnetic design for efficiency and thermal performance. The new standardized large-size core program contains E, U, I, PM and PQ cores in the N27, N87, N88, N92, N95, and N97 ferrite materials. 

These large-size ferrite cores are used in a wide range of industrial applications such as motor drives, EV charging stations, various railway/traction applications for power transformers, welding, medical, UPS, solar inverters and other renewable energy applications. Accessories like coil formers and mounting materials are available on request.


Features and benefits

 Powerful

Higher power

  • Higher power due to bigger air gaps   
  • Thicker wires for higher currents
  • Different core/material combinations
     
 Curve down

Low losses

  • Low losses with N95 at a wide temperature range (-40 °C ... +100 °C)
  • Low losses with N88 at high operating temperatures (+100 °C ... +130 °C)   
  • Specific core materials support a wide range of applications

     
 Coil Former

Special coil former

  • Coil formers for multiple stacked E-cores
  • Special geometries
  • Different coil former materials available
     
     

Large-size cores are generally used in HF power transformers, HF power chokes, HF storage chokes and power factor correction chokes (PFC).
