KMY
The KMY capacitors are a new long life, general purpose series available from United Chemi-Con.
Compared to our KME or KMG series, the KMY capacitors have a longer effective lifetime of 4,000 to
7,000 hours at 105 C with the full rated ripple current applied.
The KMY series capacitors are non-solvent proof and are not recommended when halogenated
cleaning solvents are used. Refer to the Mini-Glossary for recommended cleaning conditions.
Summary of Specifications
Radial lead terminals.
Capacitance range: 0.47 to 10,000µF.
Voltage range: 10 to 50VDC.
Operating temperature range: 40 C to 105 C.
Leakage current: 0.01CV or 3µA, whichever is greater, after 2 minutes at 20 C.
Standard capacitance tolerance: 20%
Nominal case size (D L): 5 11.5mm to 18 35.5mm.
Rated lifetime: 4,000 to 7,000 hours at 105 C with the rated ripple current applied,

When ordering, always specify complete catalog number for KMY 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. R33 = .33 F; 3R3 = 3.3 F;
33R = 33 F; 331 = 330 F; 332 = 3,300 F; 333 = 33,000 F ).
Lead Configuration: VB = Radial Lead Terminals.
DC Rated Voltage: Expressed in Volts (e.g. 16 = 16WVDC).
