Based on the model list you provided, the following is a detailed introduction to these 0402 packages and 10 ohm (10R) surface mount resistors:
TRL0402X2F10R0Q10Z
This is a standard metal film surface mount resistor.
Its rated power is 0.25 watts (1/4W), which is considered higher power in small packages like 0402.
The resistance accuracy (tolerance) is ± 1%, which means that the actual resistance value will be very close to the nominal 10 ohms.
The temperature coefficient (temperature drift) is ± 50 ppm/° C, indicating that the resistance is relatively stable when the temperature changes.
Suitable for general circuits that require high precision and good stability.
ELR04FV10R0ECS
This is also a standard metal film patch resistor.
Also has a rated power of 0.25 watts (1/4W).
The accuracy is also strictly within ± 1%.
The temperature coefficient is also good at ± 50 ppm/° C.
The functions and features are very similar to the TRL0402X2F10R0Q10Z mentioned above, with the main difference possibly being the manufacturer or specific series naming conventions.
EHP04JW10R0ECS
This is a thick film high-power surface mount resistor designed to provide higher power carrying capacity than standard resistors in a small size.
The rated power is 0.125 watts (1/8W), which is lower than the previous two metal film resistors, but is a common power in standard 0402 resistors.
The accuracy is slightly lower, at ± 5%.
The temperature coefficient is ± 100 ppm/° C, which means that the resistance value will vary slightly with temperature compared to the ± 50 ppm model.
Suitable for occasions with slightly higher power requirements but less stringent requirements for accuracy and temperature drift.
EHP04FP10R0FCU
It also belongs to the thick film high-power surface mount resistor series.
The rated power has been increased to 0.2 watts (1/5W), which is a very high power level in the 0402 package.
The accuracy is good, within ± 1%.
The temperature coefficient is ± 200 ppm/° C, which is relatively high, indicating that the resistance is greatly affected by temperature.
The characteristic is high power (0.2W), suitable for circuits with limited space but requiring high current or power, and the requirements for temperature drift can be relaxed.
EHP04JP10R0ECU
It is also a thick film high-power surface mount resistor.
The rated power is 0.2 watts (1/5W), the same as the previous model.
The accuracy is ± 5%.
The temperature coefficient is ± 100 ppm/° C.
Provides a combination of high power (0.2W) and moderate temperature drift (± 100ppm), with low precision requirements.
EHP04JP10R0FCU
Both belong to the thick film high-power surface mount resistor series.
The rated power is also 0.2 watts (1/5W).
The accuracy is ± 5%.
The temperature coefficient is ± 200 ppm/° C.
The characteristics are high power (0.2W), low precision requirements (± 5%), and large temperature drift (± 200ppm). Compared with EHP04FP10R0FCU, the main difference lies in accuracy (± 1% vs ± 5%).
EAM04FW10R0DCS
This is a metal film sulfide resistant surface mount resistor. Its core design is to resist sulfide corrosion failure caused by sulfur-containing environments.
The rated power is 0.125 watts (1/8W) of standard 0402.
High accuracy, within ± 1%.
The temperature coefficient is good, at ± 50 ppm/° C.
The core feature is sulfur resistance, suitable for applications that may be exposed to sulfur-containing gas environments (such as certain industries, automobiles, coastal or hot spring areas), requiring high reliability and prevention of sulfide erosion.
EHP04FP10R0ECU
Belongs to the thick film high-power surface mount resistor series.
The rated power is 0.2 watts (1/5W).
The accuracy is ± 1%.
The temperature coefficient is ± 100 ppm/° C.
This is an option with high precision (± 1%) and moderate temperature drift (± 100ppm) in the thick film high-power series, with a power of 0.2W. Compared with EHP04FP10R0FCU, the temperature drift is smaller (± 100ppm vs ± 200ppm).
EHP04FW10R0ECS
It is also a thick film high-power surface mount resistor.
The rated power is 0.125 watts (1/8W) according to the standard.
The accuracy is ± 1%.
The temperature coefficient is ± 100 ppm/° C.
Provides good accuracy (± 1%) and moderate temperature drift (± 100ppm) at standard power levels.
EAM04FV10R0DCS
This is a metal film sulfide resistant surface mount resistor, in the same series as EAM04FW10R0DCS.
The rated power is 0.25 watts (1/4W), which is higher than the EAM04FW10R0DCS of the same series (0.125W).
The accuracy is ± 1%.
The temperature coefficient is ± 50 ppm/° C.
The core feature is sulfur resistance and provides higher power (0.25W) and excellent temperature drift (± 50ppm), suitable for harsh environments that require high reliability, sulfur resistance, and slightly higher power requirements.
Summarize key points:
The power difference is significant: from the standard 0.125W (1/8W) to the higher 0.25W (1/4W), and then to the high-power thick film 0.2W (1/5W).
There are various precision options available: ± 1% (high precision) and ± 5% (conventional precision).
Wide temperature drift range: from very stable ± 50 ppm/° C (metal film) to ± 100 ppm/° C (common for thick films) and ± 200 ppm/° C (higher for thick films).
Technical type:
Metal film: usually with high accuracy (± 1%) and low temperature drift (± 50ppm), representative models such as TRL, ELR, EAM.
Thick film high power: It can provide higher power (especially 0.2W) in small sizes, but the temperature drift is usually large (± 100ppm or ± 200ppm), with precision options of ± 1% and ± 5%, representing the model prefix EHP.
Special Features:
Sulfurization resistance: The EAM series is specifically designed to resist corrosion in sulfur-containing environments, providing high reliability with options of 0.125W and 0.25W.
Selection suggestion:
Pursuing high precision and stability: Choose metal film (± 1%, ± 50ppm), such as TRL, ELR, EAM (if sulfurization resistance is required).
Need to withstand greater power in a small space: Choose the thick film high-power EHP series (0.2W), and select the specific model based on accuracy (± 1% or ± 5%) and temperature drift (± 100ppm or ± 200ppm) requirements.
Working in environments with sulfur-containing or high reliability requirements: it is necessary to choose the anti sulfurization series EAM.
Conventional application, cost sensitive: optional standard power (0.125W or 0.25W) thick film or metal film, accuracy and temperature drift requirements can be appropriately relaxed (such as ± 5%, ± 100ppm).
Please choose the appropriate model based on your specific application scenario (power requirements, accuracy requirements, operating temperature range, presence of sulfides in the environment, cost, etc.). Be sure to consult the manufacturer's latest data manual to confirm specific parameters and performance.
