Part Numbering Rule
YSVTM – 48 – F – 06 – M – 40A – L – - – -
YSVTMIsolated, non-regulated microchip series
48Input voltage: 26–55 V
FPackage: FULL CHIP
06Output voltage, e.g. 06 = 6 V, 08 = 8 V, 9V6 = 9.6 V
MTemperature grade — M: Tc −55~100 °C, Ts −65~100 °C · H: Tc −40~100 °C, Ts −55~100 °C · T: Tc −40~100 °C, Ts −40~100 °C
40AOutput current, e.g. 12A5 = 12.5 A, 40A = 40 A
LPin type: L = surface mount, T = through-hole
-Version: default = digital, A = analog
-Custom code: default = standard, 01 = other
