U36D is Series Name: Indicates Basic Capacitor Design.
400 is DC Rated Voltage: Expressed in Volts (e.g. 400 = 400WVDC).
LG is Lead Configuration: LG = Screw Terminals.
182 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. R18 = .18µF; 1R8 = 1.8µF; 18R = 18µF; 181 =
180µF; 182 = 1,800µF; 183 = 18,000µF).
M is Capacitance Tolerance: M = ±20%
63X79 is Case Code: Expressed in Millimeters. See Tables for inch/mm
sizes.
HP is Lead Code:
HP = High Post 10-32 Screw Thread (Standard).
LP = Low Post
10-32 Screw Thread.
CP = Low Post, High Current 1/4-28 Screw Thread.
(Available only for 0D2.500 and 0D3.000)
ML = Low Post M5 Screw
Thread.
LL = High Post M5 Screw Thread.
CC = High Post, High Current,
M6 Screw Thread. (Available only for 0D3.500)
Note: 0D3.500 available
with lead codes LL or CC only.
