4、 Other model specifications
TSL120610F1R10P05Z: Specific parameters were not matched in the search results, possibly for the early thick film series of Tian'er. It is recommended to prioritize the metal film model (EGM/TGL).
ELR16FT1R10DES/EAM16FT1R10DES: The parameters are not explicitly mentioned and may be from other series of Yineng. It is necessary to verify whether the surge resistance and temperature coefficient meet the standards.
Selection tip: In automotive electronics or industrial control, prioritize models with AECQ200 certification (such as the EGM series); Consumer electronics can focus on cost and choose the Tian'er TRL series to balance budget and precision requirements.
