Based on your needs, the following are selected recommendations for the 2512 1K high-power resistor, classified by application scenarios:
Precise control scenario (1% accuracy)
EHP25FS1K00EDS (Ellon 2W 100ppm): Suitable for analog circuits that require high-precision control, with excellent temperature drift control
EHP25FR1K00EDU (Ellon 3W 100ppm): power increased to 3W, maintaining high precision characteristics, suitable for scenarios that balance power and accuracy
CRH2512F1K00E04Z (Tian'er 2W 100ppm): a high-quality domestic choice with outstanding cost-effectiveness
Cost sensitive applications (5% accuracy)
EHP25JR1K00EDU (Ellon 3W 100ppm): Best temperature drift control for 3W power, suitable for power circuits that require a certain level of accuracy
EHP25JS1K00EDS (Ellon 2W 100ppm): A cost-effective choice for the 2W power range
Application in high temperature environment
EHP25FR1K00FDU (Ellon 3W 200ppm): 200ppm temperature drift suitable for working environments with large temperature fluctuations
EHP25JR1K00FDU (Ellon 3W 200ppm): 3W power+high-temperature float combination, suitable for harsh environments such as industrial control
It is recommended to prioritize the Ellon brand, which has a complete product line and excellent temperature drift control. If a domestic solution is needed, the Tian'er CRH2512 series is a reliable choice. Specific selection recommendations should be comprehensively considered based on the accuracy requirements, power margin, and temperature environment of the actual circuit.
