KRE Series
The KRE series capacitors are designed for use in ultra miniature applications, as the nominal height
is 5mm. Some of the applications in which these capacitors could be used are the following: camera,
car audio, mini-audio sets and other industrial and commercial units where a very low profile product
is required.
The KRE series capacitors were developed to withstand HCFC cleaning agents for two 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.

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 100F or more. R indicates the decimal point for
capacitance less than 100F (e.g. R47= .47F; 4R7= 4.7F;
47R = 47F; 471= 470F; 472 = 4,700F; 473 = 47,000F).
Lead Configuration: VB = Radial Lead Terminals.
DC Rated Voltage: Expressed in Volts (e.g. 35 = 35WVDC).
Series Name: Indicates Basic Capacitor Design.
Part Numbering System for KRE Series When ordering, always specify complete catalog number for KRE Series.
