Feature
1. Thick film non-inductive power resistors are generally attached to the system radiator to enhance the heat dissipation of the resistor. Here, because the resistor bottom plate is attached to the system radiator, the resistor dissipates the heat through the heat exchange between the bottom plate and the radiator. The ambient temperature here refers to the temperature of the resistor bottom plate, generally based on the center of the bottom plate. The temperature is a reference.
2. Power level: 50W
3. It is non-inductive, resistant to high voltage, small size and high power, long life, good moisture resistance, and stable electrical performance.
4. Lead-out ends are led out with tinned copper wire
Structure
1. Using the screen printing method, the printed layer is a resistive film with a thickness of tens of microns, which is sintered at a high temperature. The matrix is 96% aluminum oxide ceramics, which has good thermal conductivity and high mechanical strength. The resistive film layer adopts noble metal ruthenium-based slurry, and the electrical performance is stable.
2. The process flow is generally electrode printing→electrode sintering→resistance printing→resistance sintering→medium printing→medium sintering, and then made through the processes of resistance adjustment, welding, encapsulation, etc.
