|EAM16FT3R60DES | Billion Energy | Anti sulfurization, compliant with RoHS/REACH | Sulfur containing environment, industrial sensors | Unclear (reference to similar products about ¥ 0.35/piece) | Inventory 35, excess demand 20250724 | Anti sulfurization design<br>Limitations: Surge capability not clearly defined|
|ELR16FT3R60DES | Energy | Parameters unclear | Data manual to be verified | Not publicly available | Not publicly available | Caution needed: Surge/sulfur resistance characteristics not mentioned|
2、 Recommended models based on application scenarios
High wave protection scenario (industrial power supply/automotive electronics):
Preferred: EGM16FT3R60DES (Yineng)
Reason: Through IEC 6100045 certification, the surge withstand capability is 35% higher than that of ordinary resistors, and the heat dissipation efficiency is improved by 22%. It is suitable for high-frequency impulse circuits such as automotive OBC and industrial frequency converters.
Alternative: TGL120610F3R60P05Z (Day 2)
Reason: Vehicle certification+anti surge design, suitable for photovoltaic MPPT or energy storage converters.
Sulfur/high humidity environment (chemical/outdoor equipment):
Preferred: TSL120610F3R60P05Z (Tian'er)
Reason: The special metal film layer is resistant to sulfide corrosion, with the lowest unit price (¥ 0.32) and sufficient inventory.
Alternative: EAM16FT3R60DES (Yineng)
Reason: Anti sulfurization design, but with limited inventory and unverified surge capability.
Cost sensitive consumer electronics:
Preferred: TRL120610F3R60P05Z (Tian'er)
Reason: Universal metal film resistor, with a unit price of only ¥ 0.24 and a temperature drift of ± 50ppm/℃, meets basic requirements.
Precision instruments (medical/communication):
Not recommended models in the list:
Although the TRL series has low-temperature drift, it does not have anti-interference certification; It is recommended to choose the Tian'er TRL series (noise<5 μ Vrms), but the resistance compatibility needs to be confirmed.
3、 Explanation of eliminated models
ELR16FT3R60DES：
Specific parameters were not matched in the search results, which may be a niche or new model without surge/sulfurization protection data, posing design risks.
General trap reminder:
The anti surge model (such as EGM/TGL) cannot replace the anti sulfurization model (such as TSL/EAM), as their protection mechanisms are different.
Unverified models (such as TRL) may lead to early failure in automotive/industrial systems.
4、 Procurement and Production Suggestions
Priority delivery time: Choose TSL120610F3R60P05Z (Day 2), stock 5000 can be shipped immediately.
Mandatory requirement for vehicle regulations: Choose EGM16FT3R60DES (Yineng), supply in bulk in early July, and prepare materials in advance.
Cost optimization: Choose TRL120610F3R60P05Z (Tian'er) for consumer electronics, but bear the risk of delayed delivery in November.
