100W Thick Film Power Resistor High Power For Clip Mount
Thick Film High Power Resistor For High-Frequency & Pulse-Loading ,
for Mounting onto a Heatsink,Thick Film Technology
Structure
1.The resistor film with precious metal ruthenium slurry,with stable electrical properties.
2.The completely encapsulated and insulated package for low ohmic value and Non-Inductive design for high-frequency and pulse-loading applications.
3.Non-Inductive,Resistance-high voltage,small size,high power,long life,Moisture Resistance,High Stability.
4.The component is used in direct contact with heatsink.Fixation done by clip,designed for clip mounting;
5.Ideal use for power supplies,mounted to a heat sink.
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.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.
