Product Details
Heat Sink Mountable Non-inductive Thick Film High Power Resistors ,
for Mounting onto a Heatsink,Thick Film Technology
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.Technological Process: electrode printing electrode sintering
resistor printing resistor sintering medium printing medium
sintering, then resistance adjustment, welding,encapsulation and
other processes.
Features
1.Recommendations for mounting onto a heatsink to enhance the heat
dissipation.Thick Film Resistor for high-frequency and
pulse-loading applications;
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.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.
3.Non-Inductive,resistance-high voltage,small size,high power,long
life,moisture Resistance,high stability.
