Engineering Bulletin Dec 02
The LXM series capacitors are new high voltage, long life snap-in capacitors from United Chemi-Con
that are downsized replacements for the LXG snap-in capacitors rated above 100 volts. With the
improved characteristics of higher CV per case size and an extended rated lifetime of 7,000 hours
at 105 C with the rated ripple current applied, these LXM capacitors are recommended for new
designs in place of LXG capacitors greater than 100 volts. Available in a standard voltage range of 160
to 450 volts and a capacitance range of 47 to 2,200µF, the LXM series is suitable for high reliability,
high voltage applications. The LXM capacitors have a standard 2-pin snap-in terminal style.
SNAP MOUNT-105 C
The standard LXM 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.

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: VS = 2- Pin Snap-in Terminals.
DC Rated Voltage: Expressed in Volts (e.g. 350 = 350WVDC).
Series Name: Indicates Basic Capacitor Design.
