6、 Selection decision tree
Normal environment → Priority CRH/TRL series (high cost-effectiveness)
Power protection → Choose TGL anti surge series
High precision requirements → TRL metal film series (1% precision)
High current scenario → CHH high-power series (4W)
High sulfur environment → EAM anti sulfurization series (1.5 Ω model needs to be confirmed)
matters needing attention:
Part of the models (such as EAM sulfur resistant series) require confirmation of specific resistance inventory through distributors.
It is recommended to verify whether the EHP series supports AEC-Q200 certification and 1.5 Ω specification for vehicle level requirements.
