All-metal resistor series supplies higher power rating in miniature footprint

Achieving high power in compact form factors is a growing challenge in the design of power supplies and control systems. Stackpole Electronics' CSSU Series stands out with an outstanding 5W power rating in a standard 2512 chip size – performance rarely seen in this footprint.

This breakthrough is made achievable by its robust all-metal construction, which not only allows higher power handling but also greatly reduces thermal resistance. Using special thermally conductive materials and design, the resistor minimises thermal stress on surrounding components and the PCB, ensuring superior long-term stability and reliability compared to similar shunt resistors of this size.

The resistor is available in resistance values from 1mΩ to 10mΩ, in tolerances as low as 1% and 50ppm TCR. For designs pushing the limits of power density, the device offers a truly unique solution.

In addition to its impressive power handling, the AEC-compliant CSSU2512 is designed for long-term reliability. The robust metal body structure eradicates concerns over mechanical or solder joint stress caused by board flex or temperature gradients, making it an excellent solution for demanding power management and control applications where durability and performance are paramount.
