The TPAL1331 is a planar non-inductive power resistor, also known as a TO-220 package high-power resistor. It features a bottom-mounted heatsink flange for enhanced heat dissipation and balanced thermal characteristics. This resistor is designed for applications such as current detection, energy absorption and dissipation, RC absorption, high-speed switching, and high-frequency circuits. It is also commonly used in voltage regulation, constant power loads, and low-energy pulse loads. Industries benefiting from this product include industrial lasers, welding equipment, test equipment, instrumentation, UPS, automotive, and switching power supplies.

Use thermal grease or a thermal pad between the resistor flange and the heatsink. Use screws with spring washers for secure connection. Recommended mounting torque is < 1.8 Nm. For full power applications, water or oil cooling is recommended to maintain flange temperature 36C.
50 pcs per tube. Tubes are sealed with tape and packed into a box (approx. 560*110*96mm).
The rated power of 46W is based on a flange temperature of 36C. The flange temperature is a critical indicator of heat dissipation. Proper thermal design, calculation, and measurement are essential to prevent resistor failure due to overheating.
Customers must select an appropriate heatsink based on the operating conditions (power, ambient temperature). The maximum operating temperature for TPAL1331 is 210C. Calculations for heatsink selection should consider thermal resistance values (junction-to-case, case-to-heatsink, heatsink-to-ambient).
