Screw Terminal Aluminum Electrolytic Capacitors
PEH169 Series, +85°C
Overview
Applications
Typical applications for KEMET's PEH169 capacitor
include smoothing, energy storage or pulse operation in
telecommunication demanding power supplies, process
control, AC motor control, traction, welding, and measuring.
KEMET's PEH169 Series is a long-life electrolytic capacitor
with outstanding reliability and electrical performance. The
device has a polarized all-welded design, heavy duty screw
terminals, extended cathode construction, safety vent, and
plastic insulation. The PEH169 Series winding is housed
in a cylindrical aluminum can with a reinforced molded lid
incorporating a safety vent. The sealing system is designed
for electrolyte leakage-free operation and a very low gas-
diffusion rate of electrolyte. Mechanical contact between
the winding and case allows excellent heat transfer from
the winding to the ambient, which means cooler operation.
Low ESR is the result of a low resistive paper/electrolyte
system, at least two tabs per foil and an all-welded design.

Screw Terminal Aluminum Electrolytic Capacitors – PEH169 Series, +85°C
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 series 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; thus, 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 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
