  • LM74502-Q1: Typical Surge Stopper Application Cvs Value

    TI Thinks Resolved
    Part Number: LM74502-Q1 Tool/software: Hello, For BOM optimization we have decided to use Cvs 2u2-100V (CL32B225KCJSNNE) instead of 1u-100V (CL31B105KCHSNNE). Is 2u2 capacitor okay for the application? Best regards, Egemen Aksoy
