Installation Suggestions
Recommendations for mounting with heatsinks, including use of thermal grease/pads, spring washers, and suggested torque values. Water or oil cooling is recommended for full power applications to maintain flange temperature 30C.
Packaging Dimensions
Details on tube packaging, bundling, and outer carton dimensions.
Explanation of Rated Power and Temperature
The maximum rated power of 61W is based on a flange temperature of 30C. Flange temperature is a critical indicator of heat dissipation effectiveness. Proper thermal design, calculation, and measurement are essential to prevent component failure due to poor heat dissipation.
Heatsink Selection
Guidance on selecting appropriate heatsinks based on power usage, ambient temperature, and thermal resistance calculations. The maximum operating temperature for TPAN1331 series resistors is 261C.
