Screw Terminal Aluminum Electrolytic Capacitors
PEH200, +85°C
Overview
Applications
Typical applications for KEMET's PEH200 capacitor include
uninterruptible power supplies (UPS), ground power units
(GPU), welding equipment, and drives where high current
ratings and compact size are important.
The KEMET PEH200 capacitors have polarized all-welded
design, heavy duty screw terminals, extended cathode
construction, safety vent, and plastic insulation. The
sealing system is designed for electrolyte leakage-
free operation and a very low gas-diffusion rate of an
electrolyte. Mechanical contact between the winding
and aluminum case allows excellent heat transfer from
the winding hot-spot to the ambient, which means cooler
operation and very high current ratings.

Case Polarity
Due to the presence of electrolyte in the capacitor, the aluminum can and stud mounting will essentially be at the same
polarity as the negative terminal. We recommend that the stud and can be insulated (see accessories for insulating nuts).
Shelf Life
The capacitance, ESR and impedance of a capacitor will not change significantly after extended storage periods, however,
the leakage current will very slowly increase. KEMET products are particularly stable and allow a shelf life in excess of three
years at 40°C. See sectional specification under each product for specific data.
Re-age (Reforming) Procedure
Apply the rated voltage to the capacitor at room temperature for a period of one hour, or until the leakage current has fallen
to a steady value below the specified limit. During re-aging, a maximum charging current of twice the specified leakage
current or 5 mA (whichever is greater) is suggested.

Reliability
The reliability of a component can be defined as the probability that it will perform satisfactorily under a given set of
conditions for a given length of time.
In practice, it is impossible to predict with absolute certainty how any individual component will perform. Therefore, we
must utilize probability theory. It is also necessary to clearly define the level of stress involved (e.g., operating voltage, ripple
current, temperature and time.) Finally, the meaning of satisfactory performance must be defined by specifying a set of
conditions which determine the end of life of the component.
Reliability as a function of time, R(t), is normally expressed as: R(t) = e-
λt
,where R(t) is the probability that the component will
perform satisfactorily for time t, and λ is the failure rate.
Failure Rate
The failure rate is the number of components failing per unit of time. The failure rate of most electronic components follows
the characteristic pattern:
• Early failures are removed during the manufacturing process.
• The operational life is characterized by a constant failure rate.
• The wear out period is characterized by a rapidly increasing failure rate.
The failures in time (FIT) are given with a 60% confidence level for the various type codes. By convention, FIT is expressed
as 1 x 10
-9
failures per hour. Failure rate is also expressed as a percentage of failures per 1,000 hours, e.g., 100 FIT = 1 x 10
-7
failures per hour = 0.01%/1,000 hours.
End of Life Definition
Catastrophic Failure: short circuit, open circuit or safety vent operation
Parametric Failure:
• Change in capacitance > ±10%
• Leakage current > specified limit
• ESR > 2 x initial ESR value
