KMX
The KMX is a long life, low impedance series from United Chemi-Con. These capacitors have a load
life of 8,000 to 10,000 hours at 105 C with the full rated ripple current applied and a voltage range
from 160 to 450 volts. The KMX capacitors are ideal for use in electronic ballasts or any other high
voltage application where a very long lifetime is required. The KMX series capacitors are available in
slender case sizes with 10 to 18mm diameters and 20 to 60mm lengths.
The KMX series capacitors are non-solvent proof. Refer to the Mini-Glossary for cleaning guidelines
and recommended cleaning agents that are compatible with United Chemi-Con products.

LL
Lead Length: 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. R33 = .33 F; 3R3 = 3.3 F;
33R = 33 F; 331 = 330 F; 332 = 3,300 F; 333 = 33,000 F ).
Lead Configuration: VB = Radial Lead Terminals.
DC Rated Voltage: Expressed in Volts (e.g. 250 = 250WVDC).
Series Name: Indicates Basic Capacitor Design.
