MFK is Series Name: Indicates Basic Capacitor Design.
4 is Lead Length: TP is for Standard Taping.
FC is Case Code: See Case Sizes in Tables.
68R is Capacitance Tolerance: M = ±20%
M 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. R68 = .68µF; 6R8 = 6.8µF; 68R = 68µF; 681 =
680µF; 682 = 6,800µF; 683 = 68,000µF).
D8 is Lead Configuration: FC = Horizontal Chip Lead Terminals.
TP is DC Rated Voltage: Expressed in Volts (e.g. 4 = 4WVDC).
