NOTES: 1. OCL, Cww and LL are measured at 20 mVrms, 100 kHz. 2. To order Tape & Reel packaging for surface mount parts, add the suffix "T" to the part number. Example: PE-65454T. The "T" will appear on all paper work, but will not be marked on parts. 3. Part numbers denoted "EX" are extended temperature parts -40C to 85C, electrical specifications @ 25C.
