2512 10R resistor parameter model and detailed analysis of characteristics

Based on the provided Ellon brand 2512 packaged 10 Ω resistor data, it can be expanded and explained into the following five categories according to technical characteristics:
Metal film conventional series
ELR25FS10R0DDS adopts metal film technology, with a rated power of 2W and 1% accuracy, and a temperature drift control of 50ppm/℃. This model is suitable for precision circuits that require high temperature stability, such as signal conditioning or voltage division scenarios. Its sister model ELR25FR10R0DDS increases power to 3W, maintaining the same accuracy and temperature drift characteristics, making it suitable for applications that require higher power density.
Thick film high-power series
As a representative of thick film technology, EHP25FR10R0FDU performs outstandingly in cost sensitive high current scenarios with a power of 3W, 1% accuracy, and 200ppm temperature drift. There are multiple variants of this series: EHP25JR10R0EDU relaxes the tolerance to 5% and optimizes the temperature drift to 100ppm, suitable for power distribution scenarios with low precision requirements; EHP25JS10R0EDS returns to 2W power but maintains 5% accuracy, with a temperature drift control of 100ppm, forming a combination configuration of power accuracy temperature drift. Of particular note is the EHP25JR10R0FDU, whose combination of 200ppm temperature drift and 5% precision provides a cost-effective advantage in applications with significant temperature rise, such as motor control or LED driving.
Surge resistant metal film series
EGM25FS10R0DDS enhances surge withstand capability on the basis of metal film, with a power of 2W, 1% accuracy, and 50ppm temperature drift, suitable for industrial control scenarios that require transient overvoltage response. The EGM25FR10R0DDS increases power to 3W while maintaining the same surge resistance characteristics, making it suitable for higher energy impact environments. EGM25FU10R0DDS achieves a breakthrough power of 3.5W, combined with 1% accuracy and 50ppm temperature drift, providing a solution for situations that require both high power and surge protection.
Anti sulfide metal film series
EAM25FS10R0DDS is designed for sulfur-containing environments and features a special protective coating that effectively resists sulfide corrosion while maintaining 2W power, 1% accuracy, and 50ppm temperature drift. This feature makes it the preferred choice for harsh environments such as petrochemicals and automotive engine compartments.
Thick film power optimization series
EHP25FS10R0EDS is a power optimized model for thick film technology, with a 2W power combined with 1% precision and 100ppm temperature drift, forming a balance point between precision and cost. Its temperature drift parameter is between that of conventional thick films and metal films, making it suitable for applications with moderate temperature coefficient requirements.
These models together form a complete product line covering precision, power, and environmental adaptability. Users can choose based on the power requirements, accuracy requirements, environmental factors, and cost considerations of specific application scenarios. For example, when it is necessary to meet the requirements of 3W power, 1% accuracy, and 50ppm temperature drift simultaneously, ELR25FR10R0DDS and EGM25FR10R0DDS form complementary options, with the former focusing on conventional applications and the latter enhancing surge protection capabilities.
