Sense resistor power rating increased to 3W

Attaining high-efficiency current sensing demands shunt resistors that combine low resistance values with robust power handling. However, finding sense resistors that deliver a high power-to-size ratio and affordable pricing can often be challenging.

Stackpole’s CSNL2512 series manages this challenge by providing an impressive 3W power rating in a compact package, with low TCR and resistance values as low as 0.2 milliohms. This balance of performance and cost-effectiveness makes the series a standout solution for demanding applications.

Key advantages of the AEC-compliant CSNL2512 include exceptional stability. The resistance change of less than 1% across a range of industry-standard tests, including load life, short-time, overload, and biased humidity. High power density enables reliable performance in compact designs, helping to decrease overall system size and weight.

The combination of high power and low resistance values makes the CSNL ideal for applications such as EVs, power tools, HVAC controls, instrumentation, programmable power supplies, networking and infrastructure equipment, and communications equipment.
