Aluminum Housed - Power Resistors

The component being described here is characterized by a set of features. It is built with complete welded construction, ensuring durability and reliability. In addition, there are non-inductive types available for specific applications. The terminations vary depending on the power rating: for 25W to 150W resistors, solderable terminations are used, while for 200W to 500W resistors, M5 screws are used for termination. It is important to note that these resistors must be mounted on external heatsinks that are suitable for their power ratings. This ensures efficient heat dissipation and prevents overheating. Furthermore, the component exhibits good surge and pulse performance, making it suitable for applications that involve sudden voltage spikes or pulses. Lastly, it is worth mentioning that custom-designed resistors and assemblies are available, providing flexibility for specific requirements or unique applications. This allows for tailored solutions to meet individual needs.
