SME is Series Name: Indicates Basic Capacitor Design.
25 is DC Rated Voltage: Expressed in Volts (e.g. 25 = 25WVDC).
VB is Lead Configuration: VB = Radial Lead.
472 is Capacitance Value: Expressed in microfarads. The first two
digits are significant figures, and the third digit indicates the number of
zeros for capacitance of 100µF or more. R indicates the decimal point for
capacitance less than 100µF (e.g. R47 = .47µF; 4R7 = 4.7µF; 47R = 47µF; 471 =
470µF; 472 = 4,700µF; 473 = 47,000µF).
M is Capacitance Tolerance: M = ±20%
18X35 is Case Code: See Case Sizes in Tables.
LL is Lead Length: LL is Standard.
