Based on the model parameters of the 0805 package 1 Ω resistor you provided, I have compiled the following (presented by performance characteristics):
1、 Metal film high-power series (low-temperature float/high power)
1. ELR08FU1R00DES（Ellon）
Power: 0.5W
Accuracy: ± 1%
Temperature drift coefficient: ± 50ppm/℃
Technology: Metal film
2. EAM08FU1R00DES（Ellon）
Power: 0.5W
Accuracy: ± 1%
Temperature drift coefficient: ± 50ppm/℃
Technology: Metal film
3. ELR08FV1R00DES（Ellon）
Power: 0.25W
Accuracy: ± 1%
Temperature drift coefficient: ± 50ppm/℃
Technology: Metal film
Advantages: Extremely low temperature drift (50ppm/℃), suitable for circuits with high temperature stability requirements, and the 0.5W model can withstand higher power.
2、 Thick film high-power series (conventional power/multiple temperature drifts)
Standard accuracy (± 1%)
1. CRH0805F1R00P05S (Day 2)
Power: 0.25W
Accuracy: ± 1%
Temperature drift coefficient: ± 400ppm/℃
2. EHP08FU1R00HEU（Ellon）
Power: 0.5W
Accuracy: ± 1%
Temperature drift coefficient: ± 400ppm/℃
3. EHP08FV1R00FES（Ellon）
Power: 0.25W
Accuracy: ± 1%
Temperature drift coefficient: ± 200ppm/℃
Low precision (± 5%)
1. EHP08JU1R00HEU（Ellon）
Power: 0.25W
Accuracy: ± 5%
Temperature drift coefficient: ± 400ppm/℃
2. EHP08JV1R00FES（Ellon）
Power: 0.25W
Accuracy: ± 5%
Temperature drift coefficient: ± 200ppm/℃
Application suggestion:
Select a 200ppm/℃ model for low-temperature bleaching (such as EHP08FV1R00FES);
High power selection of 0.5W thick film (EHP08FU1R00HEU) is required;
Low cost scenarios can choose ± 5% precision models.
Summary of key selection points
Power demand:
0.5W metal film (ELR/EAM series) or 0.5W thick film (EHP08FU).
Temperature drift requirements:
The preferred choice for precision circuits is a 50ppm/℃ metal film;
For general scenarios, 200ppm/℃ or 400ppm/℃ thick films can be selected.
Cost balance:
High precision (± 1%) metal film thick film;
± 5% precision thick film has the highest cost-effectiveness.
It is recommended to make a comprehensive selection based on the actual power, temperature drift, and cost requirements of the circuit.
