800W Ultra High Power Resistors,for Mounting Onto a 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. 800W operating power,non-Inductive design,high insulation & partial discharge performance;
3.Connection screw thread M5(Standard M5,M4 on request);
4.Attachment to an air cooled or water cooled heat sink is necessary.
5.With low indutance,high density installation,are vibration proof and exhibit perfect heat dissipation.
6.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.
Advantages:
1.Manufacturing standard &customs design;
2.Sample order is available;
3.Immediately Response,reply you for your inquiry in 24 hours;
