Ceramic Packages

TO Ceramic Packages

Kyocera has developed new TO ceramic packages that have higher heat resistance, higher thermal conductivity, higher withstand voltage and higher current carrying capacity than conventional materials. Our products support the spread of next generation power semiconductors such as silicon carbide (SiC) which are key for energy conservation.

Notes

  1. Aluminum oxide ceramic material (Kyocera A440).
  2. Plating options: Ni plating or Ni + Au plating
  3. KYCM is a registered trademark of KYOCERA Corporation in Japan.
  4. Current carrying capacity is defined by maximum lead temperature: 80°C.
  5. High temperature storage and temperature cycling tests conducted by Kyocera. Criteria based on visual and withstand voltage specifications.

 

Large-scale hybrid packages have been developed and supplied as variations of the TO ceramic packages.
We can tailor our products to your needs.
