L
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 -40°C to 85°C, electrical specifications @ 25°C.
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.
