300W 10k Thick Film Ultra High Power Resistors For Easy Mounting
Structure
1.starting resistors 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.Surfaces in contact must be carefully cleaned.
3.Non-inductive,High power,Small size,Easy mounting,recommendations for mounting onto a water-cooled heatsink.
Features
1.Recommendations for mounting onto a heatsink to enhance the heat dissipation.
2.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.
3.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.
4.Easy mounting,low thermal radiation of the case ;
