Part Numbering Rule
YSBCM – 384W – EC – 12 – M – 125A – T – R – -
YSBCMIsolated, non-regulated microchip series
384WInput voltage: 260–410 V
ECPackage: CHIP6123 (long-side pins)
12Output voltage: 12 = 12 V, 24 = 24 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
125AOutput current: 68A = 68 A, 125A = 125 A, 62A5 = 62.5 A
TPin type: T = through-hole
RVersion: 0 = analog control, 1 = PMBus control, R = reverse analog, P = reverse PMBus
-Custom code: default = standard, 01 = other
