800W Non-Inductive High Power Resistors,Chassis Mounting

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;
