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 -40°C to 85°C, electrical specifications @ 25°C.
4. E2023NL is the RoHS compliant version of E2023.
