ΔR≤±(5%R+0.05Ω)

Radiator installation method and requirements

The resistor is installed on the radiator with 2 M4 screws, and the installation torque is less than or equal to 1.3N.m (to ensure the use of power and excellent heat dissipation);
The contact surface must be cleaned;

The flatness of the radiator is: 0.05mm-0.1mm (within the range of 100mm); The roughness of the radiator must be 6.3цm;
To improve thermal conductivity, contact surfaces (alumina, heat sinks) should be coated with silicone grease.
