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. E2023NL.
3. Part numbers denoted ”EX” are extended temperature parts -40°C to 85°C, electrical specifications @ 25°C.
4. MSL = Moisture Sensitivity Level a=1 b=2 c=3 d=4
Peak solder temperature ratings per
table 5-2 in IPC/JEDEC J-STD-020
