3D Models
PCNM series chip resistors are designed on aluminum
nitride ceramic substrates with enlarged backside
terminations to reduce the thermal resistance between the
topside resistor layer and the solder joint on the end users
circuit assembly.
Actual power handling capability is limited by the end user
mounting process. As with any high power chip resistor the
ability to remove the heat is critical to the overall
performance of the device.

Notes
• Chip surface temperature measured using FLIR SC645 thermal imaging system with an approximate test card surface temperature of 85 °C
• Thermal imaging was conducted 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 a 1.6" x 3.7" test card with 3.5 mil copper plating on both
surfaces. Thermal vias on 50 mil centers were utilized for heat transfer between surfaces of the test card
