Insulation Resistance
The insulation resistance of the sleeve will measure no less than 100 megohms with a 500VDC
potential between the mounting clamp and the sleeve. The mounting clamp shall be secured
around the sleeve of the capacitor body, and the terminals shall be shorted together.
The insulating sleeve will withstand a voltage of 2,000VAC without electrical breakdown when
the voltage is applied between the mounting clamp and the sleeve. The mounting clamp shall be
secured around the sleeve of the capacitor body, and the terminals shall be shorted together.
The following specifications shall be satisfied when the capacitors are restored to 20 C after
subjecting them to the DC rated voltage for 5,000 hours at 85 C with the rated ripple current
applied. The sum of DC voltage and peak AC voltage must not exceed the full rated voltage of
the capacitors.

LL
Terminals: LL is Standard.
Case Code: See Case Sizes in Tables.
Capacitance Tolerance: M = 20%
Capacitance Value: Expressed in Microfarads. The first two digits are
significant figures, and the third digit indicates the number of zeros
for capacitance of 100 F or more. R indicates the decimal point for
capacitance less than 100 F (e.g. R68 = .68 F; 6R8 = 6.8 F;
68R = 68 F; 681 = 680 F; 682 = 6,800 F; 683 = 68,000 F ).
Lead Configuration: LG = Screw Terminals.
DC Rated Voltage: Expressed in Volts (e.g. 350 = 350WVDC).
Series Name: Indicates Basic Capacitor Design.
