4. EAM16FT10R0DES (Billion Energy)
Series characteristics: It is speculated to be the Yineng basic metal film series (referring to the same brand of EGM).
Attention: There are few publicly available parameters, and it is necessary to verify whether they have surge resistance and AECQ200 certification. If it is a universal model, it is suitable for consumer electronics (such as power management).
5. ELR16FT10R0DES (Yineng)
Positioning: It may belong to the early series of Yineng, and its anti surge or low-temperature drift characteristics are not explicitly mentioned. It is recommended to prioritize the use of EGM or TRL series as alternatives.

Risk Warning: It may be a thick film resistor (non-metallic film) with a typical temperature drift of ± 400ppm (much higher than ± 50ppm for metal film), poor power stability, and not recommended for high reliability scenarios.
3、 Selection comparison and scene recommendation
|Model | Core Advantages | Temperature Drift (ppm/℃) | Surge Resistance | Recommended Scenarios|
|EGM16FT10R0DES | High surge resistance | ± 50 | Extremely strong (20A/10 μ s) | Automotive electronics/industrial power supply|
|TRL120610F10R0P05Z | High precision+low temperature noise | ± 50 | Medium | Medical/communication equipment|
|TGL120610F10R0P05Z | Balanced protection+high temperature resistance | ± 50 | Strong (100000 pulses) | Photovoltaic/energy storage system|
|EAM/ELR series | Cost effectiveness | To be verified | To be verified | Consumer electronics (non harsh environment)|
4、 Key considerations for selection
1. Surge resistance requirements:
Industrial/automotive scenarios (such as motor control) → Preferred EGM series (Yineng).
2. Accuracy and temperature drift:
Medical/communication equipment → TRL series (Tian'er) is preferred.
3. Cost and Supply:
Consumer Electronics → TGL Series (Tian'er) or EAM Series (Yineng).
4. Certification requirements:
Vehicle specification project → AECQ200 certified model (such as EGM) must be selected.
Ultimate suggestion: If pursuing a "versatile" (surge resistance+accuracy), EGM16FT10R0DES is the comprehensive optimal solution; If the budget is limited and high precision is required, TRL120610F10R0P05Z is more worth investing in.
