Based on the technical characteristics, application scenarios, and reliability certifications of each model, the following is a selection analysis and recommendation for the 1206 package, 3.9 Ω (3.9R), 1W power, and ± 1% precision resistor:
1、 Comparison of core model parameters and characteristics
|Model | Manufacturer | Core Features | Special Performance | Certification/Reliability | Applicable Scenarios | Price Level|
|EAM16FT3R90DES | Energy | Anti sulfur metal film | Anti sulfur corrosion, multi-layer passivation process | Compliant with ASTM B80995 | Sulfur containing environment (chemical/mining) | Medium (¥ 0.350.42/thousand pieces)|
|TRL120610F3R90P05Z | Tian Er | Universal alloy resistor | Low temperature drift (± 50ppm/℃), low noise | No special protection certification | Consumer electronics/ordinary power supply | Low price (¥ 0.230.28/thousand pieces)|
|TGL120610F3R90P05Z | Tian'er | Surge resistant metal film | High pulse withstand (IEC 6100045) | AECQ200 automotive standard | New energy/automotive electronics/photovoltaics | Medium high price (¥ 0.360.46/thousand pieces)|
|TSL120610F3R90P05Z | Tian Er | Anti sulfur thick film | Anti sulfur corrosion, high cost performance | No vehicle certification | Sulfur containing environment (LED power/outdoor) | Low price (¥ 0.32/thousand pieces)|
|EGM16FT3R90DES | Energy saving | High surge resistant metal film | Resistant to 20A/10 μ s surge, heat dissipation efficiency+22% | AECQ200 automotive standard | Industrial frequency converter/automotive OBC | High price (¥ 0.400.48/thousand pieces)|
|ELR16FT3R90DES | Energy | Unclear (suspected to be universal) | Parameters not detailed, may not have special protection | No public certification information | To be verified | Unknown|
Note:
The ELR series did not match clear parameters in the search results and may be an early universal series of Yineng. It is recommended to prioritize the EAM or EGM series.
Price reference: Calculated based on the bulk purchase price of similar resistance models (such as 1.1 Ω/1.5 Ω).
2、 Selection suggestion: prioritize selection according to application scenarios
Automotive Electronics/Industrial Control (High Wave Environment)
Preferred model: EGM16FT3R90DES (Yineng)
Reason: Passed AECQ200 certification, with leading surge resistance (able to withstand 20A/10 μ s pulses), heat dissipation efficiency 22% higher than ordinary resistors, suitable for new energy vehicle OBC, industrial frequency converters and other scenarios.
Second choice model: TGL120610F3R90P05Z (Tian Er)
Reason: Through AECQ200, the surge protection is balanced and the cost-effectiveness is slightly higher than that of the Yineng EGM series.
Sulfur containing/high humidity environment (chemical/outdoor equipment)
Preferred model: EAM16FT3R90DES (Yineng)
Reason: The sulfur resistance meets the ASTM B80995 standard, and the lifespan is more than three times that of ordinary resistors. It is suitable for equipment in mining, chemical, or humid and hot areas.
Cost effective alternative: TSL120610F3R90P05Z (Tian Er)
Reason: Anti sulfurization design, priced about 20% lower than EAM, suitable for cost sensitive sulfur-containing scenarios such as LED power supplies.
Consumer electronics/ordinary power supply (low-cost demand)
Preferred model: TRL120610F3R90P05Z (Tian Er)
Reason: Universal alloy resistor, low temperature drift (± 50ppm/℃), lowest price (about ¥ 0.230.28/piece), suitable for fast charging adapters, computer motherboards, etc.
Models to avoid:
ELR16FT3R90DES: The parameters are not clear, there is no reliability certification, and there is a risk of application.
3、 Summary of Key Indicator Differentiation
Surge resistance: EGM (Billion Energy)>TGL (Tian'er)>Other series (measured surge life of EGM exceeds 100000 times).
Sulfurization resistance: EAM (Yineng)>TSL (Tian'er) (EAM uses SiO ₂ composite protective layer for more thorough sulfur prevention).
Temperature drift and accuracy: All models meet the requirements of ± 50ppm/℃ and ± 1%, but the TRL series has lower noise (<5 μ Vrms) and is more suitable for precision signal acquisition.
Cost ranking: TRL (lowest) → TSL → EAM → TGL → EGM (highest).
Overall optimal: EGM16FT3R90DES (Yineng) - balancing vehicle grade reliability, surge resistance, and wide temperature stability, suitable for high demand industrial and automotive scenarios.
Cost priority: TRL120610F3R90P05Z (Tian Er) - meets basic performance and has the lowest price, suitable for consumer electronics.
Attention: During actual procurement, it is necessary to confirm the supplier's inventory and delivery cycle (e.g. TGL series requires 6-week ordering), and request the official data manual to verify the temperature rise curve and pulse test report.
