NOTES:
1. OCL, Cww and LL are measured at 20 mVrms, 100 kHz.
2. For Tape & Reel packaging, add a 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 Add suffix NL for RoHS compliant parts, e.g: E2023 changes to E2023NL or E2023NLT (for Tape & Reel).
5. Contact Pulse for RoHS compliant part availability.
6. MSL=Moisture Sensitivity Level a=1 b=2 c=3 d=4 e=5.
