1. OCL, Cww and LL are measured at 20 mVrms, 100 kHz.
2. For Tape & Reel packaging, add the suffix T to the end of the part number when ordering. e.g. E2023T.
3. Part numbers denoted EX are extended temperature parts -40C to 85C, electrical specifications @ 25C.
4. E2023NL is the RoHS compliant version of E2023.
