Stackpoleâs CSSU2512 Offers True 5 Watt Power Rating
10 April 2026 Achieving true high power in a compact footprint is no small feat, but Stackpole says its CSSU2512 delivers a genuine 5W rating in a standard 2512 size.
The company says its allâmetal construction and efficient thermal design utilising proprietary internal heat sink materials significantly lower thermal resistance, enabling 5W performance with thermal behavior comparable to typical 2512 current sense resistors rated at just 3 W. This advanced heat handling reduces stress on the PCB and nearby components, improving stability and longâterm reliability in highâdensity power designs. With 1–10 mΩ values, 1% tolerance, 50 ppm TCR, and AEC compliance, the CSSU2512 is built for demanding applications where high power and high reliability matter.
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 or volume pricing.
