Actual Size
The SMQ series capacitors are new downsized versions of the general purpose SMG series, but
offer an extended capacitance range from 0.1 to 47,000µF. The SMQ capacitors have a rated lifetime
of 2,000 hours at 85 C and a category temperature range of 40 C to 85 C except for the 450
volt products which have a range of 25 C to 85 C. This series is available in 9 case diameters
from 5 to 22mm and range from 11 to 50mm in length.
The SMQ 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.

35
VB

M
18X40
LL
When ordering, always specify complete catalog number for SMQ Series.*
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. R68 = .68 F; 6R8 = 6.8 F;
68R = 68 F; 681 = 680 F; 682 = 6,800 F; 683 = 68,000 F ).
Lead Configuration: VB = Radial Leads.
DC Rated Voltage: Expressed in Volts (e.g. 35 = 35WVDC).
Series Name: Indicates Basic Capacitor Design.
