LBG
The LBG series capacitors are designed for use in airbag applications. These capacitors have very
stable low temperature characteristics, which make them ideal for airbag use. The standard tolerance
of 0 to 30% also helps to meet the minimum capacitance requirements for this application.
The LBG series capacitors are solvent proof. Refer to the Mini-Glossary for cleaning guidelines and
recommended cleaning agents that are compatible with United Chemi-Con products.

LL
When ordering, always specify complete catalog number for LBG Series.
Lead Length: LL is Standard.
Case Code: See Case Sizes in Tables.
Capacitance Tolerance: S = 0% to 30%
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. R18 = .18 F; 1R8 = 1.8 F;
18R = 18 F; 181 = 180 F; 182 = 1,800 F; 183 = 18,000 F ).
Lead Configuration: VB = Radial Lead Terminals.
DC Rated Voltage: Expressed in Volts (e.g. 35 = 35WVDC).
Series Name: Indicates Basic Capacitor Design.
