KMA
The KMA series capacitors are designed for use in ultra miniature applications, as the nominal height
is 7mm. The KMA series also has a rated lifetime of 1,000 hours at 105 C. Typical applications include
video tape recorders, car audio equipment, and other personal electronic products.
The KMA series capacitors were developed to withstand HCFC cleaning agents for five minutes
by ultrasonic, vapor or immersion. This solvent proof design allows all circuit board components
to be cleaned together, at the same time, without resorting to more expensive epoxy end-sealed
capacitors. Refer to the Mini-Glossary for recommended cleaning conditions.

LL
When ordering, always specify complete catalog number for KMA 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. R47 = .47 F; 4R7 = 4.7 F;
47R = 47 F; 471 = 470 F; 472 = 4,700 F; 473 = 47,000 F ).
Lead Configuration: VB = Radial Lead Terminals.
DC Rated Voltage: Expressed in Volts (e.g. 25 = 25WVDC).
Series Name: Indicates Basic Capacitor Design.
