SMH is Series Name: Indicates Basic Capacitor Design.
200 is DC Rated Voltage: Expressed in Volts (e.g. 200 = 200WVDC).
VN is Lead Configuration: VN = Snap-in. See diagrams for terminal
options.
471 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%
22X35 is Case Code: See Case Sizes in Tables.
T2 is Terminal Code: T2 = 2-Pin Snap-in (Standard).
