Non-Inductive Thich Film High Voltage Power Resistors without coating
Structure :
1.Screen printing,resistor film printed layer with thickness of tens of microns,sintered at temperature.
The matrix is 95% aluminum oxide ceramic,with good thermal conductivity and high mechanical strength.
The resistor film with precious metal ruthenium slurry,with stable electrical properties.
2.The products are available with a silicone or epoxy coating,feature a wide range of tolerances and temperature coefficients.
Features:
1.Non-Inductive,Resistance-high voltage,small size,high power,long life,moisture resistance,high stability .
2.Lead Material:copper,tin-plated ,bolt /screw end caps ;
3.High voltage power resistors series combine proprietary non-inductive resistance system and design to achieve low temperature coefficient,low voltage coefficient,high stability,increased high operating voltages and high power ratings.
