In applications where AEC-Q200 qualified components are not required, the standard ACAS precision or standard ACAS professional series can be considered. The standard ACAS precision series offers many of the same key benefits described for the ACAS AT series such as precision tolerance matching and TCR tracking, but it is not AEC-Q200 qualified or specified against the same extreme sulfur or humidity conditions. The ACAS professional series is offered with less precise tolerance and TCR options for circuits where absolute tolerance ±0.5% or ±1% and absolute TCR ±50 ppm/°C or ±25 ppm/°C will do.
