0805 100K 0.5W/0.25W High Power Resistance Model Parameter Table

Okay, here are some high-power resistor models with 0805 package and 100K Ω resistance value that you have listed, along with their key characteristics, to avoid using tables for comparison:

1.  EHP08FU100KFEU (Ellon)
Power: 0.5W (high power)
Accuracy: 1%
Temperature Drift Coefficient (TCR): ± 200 ppm/° C
Key point: Provides high 0.5W power and high accuracy (1%) in the 0805 package, but relatively high temperature drift coefficient (200ppm).

2.  EHP08JU100KEEU (Ellon)
Power: 0.5W (high power)
Accuracy: 5%
Temperature Drift Coefficient (TCR): ± 100 ppm/° C
Key point: With a high power of 0.5W, the precision requirement is relaxed (5%), but the temperature drift coefficient is low (100ppm), making it suitable for applications that require slightly higher resistance stability but less stringent precision requirements.

3.  EHP08FV100KEES (Ellon)
Power: 0.25W (standard power is higher)
Accuracy: 1%
Temperature Drift Coefficient (TCR): ± 100 ppm/° C
Key points: The power is 0.25W (which is also a relatively high specification for 0805 packaging), with high accuracy (1%) and low temperature drift coefficient (100ppm), balancing accuracy, stability, and power.

4.  EHP08JU100KFEU (Ellon)
Power: 0.5W (high power)
Accuracy: 5%
Temperature Drift Coefficient (TCR): ± 200 ppm/° C
Key points: 0.5W high power, loose precision requirement (5%), high temperature drift coefficient (200ppm). It may be a choice in scenarios where cost and power are prioritized, and accuracy and temperature drift requirements are low.

5.  EHP08JV100KEES (Ellon)
Power: 0.25W (standard power is higher)
Accuracy: 5%
Temperature Drift Coefficient (TCR): ± 100 ppm/° C
Key points: 0.25W power, loose accuracy requirement (5%), but low temperature drift coefficient (100ppm). Suitable for situations where power requirements are not the highest, accuracy requirements are average, but stability is a certain requirement.

6.  EHP08FU100KEEU (Ellon)
Power: 0.25W (standard power is higher)
Accuracy: 1%
Temperature Drift Coefficient (TCR): ± 100 ppm/° C
Key points: The parameters are very close to EHP08FV100KEES, both with 0.25W power, 1% accuracy, and 100ppm temperature drift. Possible subtle differences within the same series (such as packaging, certification, etc.), with consistent core parameters.

7. CUH0805F100KP05Z (Tian'er Techwin)
Power: 0.5W (high power)
Accuracy: 1%
Temperature Drift Coefficient (TCR): ± 100 ppm/° C
Key point: from the Tian'er brand. Provide the highest power of 0.5W, while having high 1% accuracy and low 100ppm temperature drift coefficient. It is the best choice among these models in terms of comprehensive performance (power+accuracy+temperature drift).

Summary and selection tips:

Power priority (0.5W): If you need the maximum power that can be achieved under the 0805 package (0.5W), there are EHP08FU100KFEU (1%, 200ppm), EHP08JU100KEEU (5%, 100ppm), EHP08JU100KFEU (5%, 200ppm)  Optional with CUH0805F100KP05Z (1%, 100ppm). Among them, Tian'er's CUH0805F100KP05Z provides the best accuracy and temperature drift combination (1%+100ppm) in the 0.5W group.
Moderate power (0.25W): If 0.25W power meets the demand, EHP08FV100KEES (1%, 100ppm), EHP08JV100KEES (5%, 100ppm), and EHP08FU100KEEU (1%, 100ppm) are available for selection. EHP08FV100KEES and EHP08FU100KEEU provide better accuracy (1%) and temperature drift (100ppm).
Precision priority (1%): For applications with high precision requirements, EHP08FU100KFEU (0.5W, 200ppm), EHP08FV100KEES/EHP08FU100KEEU (0.25W, 100ppm), and CUH0805F100KP05Z (0.5W, 100ppm) can be selected. Among them, CUH0805F100KP05Z provides the highest 0.5W power and lower 100ppm temperature drift while ensuring 1% accuracy.
Temperature drift priority (100ppm): For applications that require high temperature stability, you can choose EHP08JU100KEEU (0.5W, 5%), EHP08FV100KEES/EHP08FU100KEEU (0.25W, 1%), EHP08JV100KEES (0.25W, 5%)  And CUH0805F100KP05Z (0.5W, 1%). Among them, CUH0805F100KP05Z provides the highest 0.5W power and 1% accuracy while ensuring a 100ppm temperature drift.
Cost/Relaxation Requirement (5% Accuracy): If the accuracy requirement is not high (5%), you can choose EHP08JU100KEEU (0.5W, 100ppm), EHP08JU100KFEU (0.5W, 200ppm) or EHP08JV100KEES (0.25W, 100ppm). They usually have a cost advantage.
Brand differentiation: The main brand is Ellon (South Korea), offering a variety of combinations. The last one is Techwin (China), whose CUH0805F100KP05Z model provides excellent options in the key combination of 0.5W, 1%, and 100ppm.

Final selection suggestion: It is necessary to comprehensively weigh and choose the most suitable model based on your actual power requirements, accuracy requirements, temperature stability requirements (temperature drift), cost budget, and supply channels in the design. If pursuing the top-level performance of 100K Ω resistor in 0805 package (0.5W+1%+100ppm), the CUH0805F100KP05Z from Tian'er is a very worthwhile option to consider.
