Stackpole’s all-metal resistor series offers higher power rating in miniature footprint
12th June 2025

Achieving high power in compact form factors is a growing challenge in power supply and control system design. Stackpole’s CSSU Series has an exceptional 5W power rating in a standard 2512 chip size – performance rarely seen in this footprint.
This breakthrough is made possible by its robust all-metal construction, which not only enables higher power handling but also significantly reduces thermal resistance. Through special thermally conductive materials and design, the CSSU2512 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 CSSU2512 is available in resistance values from one to 10 milliohm, in tolerances as low as 1% and 50ppm TCR. For designs pushing the limits of power density, the CSSU2512 offers a truly unique solution.
In addition to its impressive power handling, the AEC-compliant CSSU2512 is engineered for long-term reliability. The robust metal body structure eliminates concerns over mechanical, or solder joint stress caused by board flex or temperature gradients, making it an ideal solution for demanding power management and control applications where durability and performance are paramount.
Pricing for the CSSU2512 depends on resistance value and volume and ranges from $0.22 to $0.30 each in full package quantities. Contact Stackpole or one of its franchised distribution partners for specific pricing.
