3、 Selection decision tree
Accuracy priority: Choose metal film resistors (ELR/TRL series) with 1% accuracy to ensure accurate sampling.
Power demand:
1W: ELR16FTR910DES (industrial high current scenario)
0.5W: EHP16FUR910JEL (Low cost scenario for consumer electronics)
Special environment:
Vehicle specifications/sulfur resistance: TRL120610FR910P05Z (Tian Er)
High temperature/high humidity: ELR series metal film (50ppm temperature drift)
Cost optimization: Thick film resistors (EHP series) offer higher cost-effectiveness in non precision scenarios.
4、 Supplier recommendation
Ever Ohms:
Channels: Huanian Mall, Shunhai Technology (officially authorized, supporting procurement of vehicle specifications and models).
Advantage: TRL series sulfur resistant resistors are specifically designed for corrosive environments.
Ellon (Billion Energy):
Channels: Lichuang Mall, Yineng Official Flagship Store.
Advantages: The ELR series metal film resistors have both surge resistance and low-temperature drift characteristics.
5、 Market trend supplement
New energy demand: The demand for high-power resistors with a capacity of over 1W is increasing in car chargers (OBC) and photovoltaic MPPT controllers.
Vehicle regulation certification: AECQ200 has become a mandatory standard for automotive electronics selection, and the Tian'er TRL series has passed such certification.
If further parameter validation or sample acquisition is required, it is recommended to check real-time inventory through platforms such as Huanian Mall and Lichuang Mall.
