600W Thick Film Ultra High Power Resistors Cooled by Auxiliary Heatsink
Structure
1.Screen printing,resistor film printed layer with thickness of tens of microns,sintered at temperature.The matrix is 96% aluminum oxide ceramic,with good thermal conductivity and high mechanical strength.The resistor film with precious metal ruthenium slurry, with stable electrical properties.
2.600W operating power ;
3.Non-Inductive design;High insulation & partial discharge performance;
Features
1.Recommendations for mounting onto a heatsink to enhance the heat dissipation.The bottom case is attached to the system heatsink,and the resistor dissipates the heat through the heat exchange between the bottom case and the heatsink.The ambient temperature here refers to the bottom case temperature of the resistor, which is generally referred to as the temperature in the center of the bottom case.
2.Non-Inductive,Resistance-high voltage,small size,high power,long life,Moisture Resistance,High Stability.
3.Connection screw thread M5(Standard M5,M4 on request).
