Thick Film Design Ultra High Power Resistors,with height 47mm
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-800W 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).
