The KZH series is a new ultra low impedance and long life capacitor series that uses a unique water
base electrolyte. This series is designed for use in personal computers and storage equipment and is
specifically targeted for use in motherboard VRM circuits. The KZH series capacitors have a life
expectancy of 5,000 to 6,000 hours (depending on case diameter) at 105 C with the rated ripple
current applied. This high reliability series has a voltage range of 6.3 to 35 volts and a capacitance
range of 47 to 8,200µF.
The KZH 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.

When ordering, always specify complete catalog number for KZH 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 Leads.
DC Rated Voltage: Expressed in Volts (e.g. 25 = 25WVDC).
Series Name: Indicates Basic Capacitor Design.
