SXE 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 Terminals.
102 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. R10 = .10µF; 1R0 = 1.0µF; 10R = 10µF; 101 =
100µF; 102 = 1,000µF; 103 = 10,000µF).
M is Capacitance Tolerance: M = ±20%
12X25 is Case Code: See Case Sizes in Tables.
LL is Lead Length: LL is Standard.
