Designed To Withstand Demanding Environments

 

We build custom applications for many industries including the ones with tough, demanding Aviation and Marine environments. We know special consideration must be given to vibration, moisture, weight, contamination and qualification. Unique winding configurations, high-efficiency cores, high-strength and non-nutrient encapsulants.

 

That's why we work collaboratively with you and your technical personnel to to develop the optimal solution for your complex requirement.

 

Example Types of Aviation & 400Hz Inductors & Chokes:

 

  • 3-phase
  • MIL-PRF-27 design
  • Military and Aerospace
  • Sealed / Encapsulated / Molded
  • Litz and Copper Foil Windings / Amorphous and Specialty
  • Material Cores
