Substrates AL 2 O 3 / A L N Tooled / Machined

Substrate
Quick-Ohm´s insulator are protecting your power transistors with:
  • Dimensions adapted to the highest manufacturing standards
  • Efficent electricalinsulator with alumina oxide
  • Excellent heat dissipation obtained by a perfect contact between the case of the power transistor and the heat dissipater.
    Quick-Ohm ist offering the whole range of the actually used insulators. They are all available immediately. The non-standard dimensions can be obtained on special request. Our supplier also producing substrates of a thickness equal or superior to 1 mm for various applications such as potentiometer support for the automobile industry, sintering supports for MIM application, etc. They are manufactured according to the customer´s drawings.
    Do not hesitate to contact us.
