The optional power and corresponding model parameters of the 1K resistor packaged in 0603 are as follows:
0.33W (1/3W) power
EHP06FO1K00EEU: Accuracy 1%, Temperature Coefficient 100ppm, Thick Film High Power, Ellon Brand
EHP06FO1K00FEU: Accuracy 1%, Temperature Coefficient 200ppm, Thick Film High Power, Ellon Brand
EHP06JO1K00FEU: Accuracy 5%, Temperature Coefficient 200ppm, Thick Film High Power, Ellon Brand
EHP06JO1K00EEU: Accuracy 1%, Temperature Coefficient 100ppm, Thick Film High Power, Ellon Brand
1/8W (0.125W) power
EHP06FW1K00EES: Accuracy 1%, Temperature Coefficient 100ppm, Thick Film High Power, Ellon Brand
EHP06JW1K00EES: accuracy 5%, temperature coefficient 100ppm, thick film high power, Ellon brand
The above models are all packaged in 0603 and have thick film high-power characteristics, with differences mainly in power, accuracy, and temperature coefficient parameters.
