Actual power handling capability is limited by the end user mounting process. As with any high power chip resistor the ability to remove the generated heat is critical to the overall performance of the device.

  • Chip surface temperature measured using FLIR A40 thermal imaging system with an approximate test card surface temperature of 85 °C.
  • Thermal imaging was conduc ted under ambient conditions resulting in a steady state test card surface temperature of 85 °C over the full range of power levels.
  • Thermal imaging and load life testing was conducted mounting one device to 2" x 3" test ca rds with 2.5 mil copper plating on both surfaces. Thermal vias on 120 mil centers were utilized for heat transfer between surfaces of the test card. Notes
