200W 10 Ohm Precision Current Sense Ultra High Power Resistors snubber resistors
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.Non-Inductive,resistance-high voltage,small size,high power,long life,moisture resistance,high stability.
Features
1.This Series uses state of the art technology to provide highly reliable,non inductive performance. This resistor is ideal for many current monitoring and controls applications.
2.Four terminals to isolate measurement path from current flow path;Accuracy in a high power package.
3.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.
