The KMQ series is a new high voltage snap-in capacitor series from United Chemi-Con that offers
downsized versions of the current miniaturized KMM series. These capacitors have a rated lifetime of
2,000 hours at 105 C with the rated ripple current applied. With high ripple current capability and
higher CV per case size than the KMM series, the KMQ capacitors are suitable for many downsized
power supply circuits. The KMQ capacitors have a standard 2-pin snap-in terminal style. As an
option the KMQ series is available with environmentally friendly PET (polyester) sleeves and Pb-free
materials.
SNAP MOUNT-105 C
The standard KMQ 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.

Terminal Code: T2 = 2 - Pin Snap-in (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. R15 = .15 F; 1R5 = 1.5 F;
15R = 15 F; 151 = 150 F; 152 = 1,500 F; 153 = 15,000 F ).
Lead Configuration: VS = 2- Pin Snap-in Terminals.
DC Rated Voltage: Expressed in Volts (e.g. 180 = 180WVDC).
Series Name: Indicates Basic Capacitor Design.
