Screw Terminal Aluminum Electrolytic Capacitors – PEH200 Series, +85°C
MTBF
The mean time between failures (MTBF) is simply the inverse of the failure rate.
MTBF= 1/λ
early failures
wear out
operational life
Time
The failure rate is derived from our periodic test results. The failure rate (λR) is, therefore, only given at test temperature for life tests. An
estimation is also given at 60°C.
The expected failure rate for this capacitor range is based on our periodic test results for capacitors with structural similarity.
Ta
Failure Rate per Hour
85°C 1,000 FIT
60°C 100 FIT
Failure rate per hour includes both catastrophic and parametric failures.
Environmental Compliance
As an environmentally conscious company, KEMET is working continuously with improvements concerning the environmental effects
of both our capacitors and their production. In Europe (RoHS Directive) and in some other geographical areas like China, legislation
has been put in place to prevent the use of some hazardous materials, such as lead (Pb), in electronic equipment. All products in this
catalog are produced to help our customers’ obligations to guarantee their products and fulfill these legislative requirements. The only
material of concern in our products has been lead (Pb), which has been removed from all designs to fulfill the requirement of containing
less than 0.1% of lead in any homogeneous material. KEMET will closely follow any changes in legislation world wide and makes any
necessary changes in its products, whenever needed.
Some customer segments such as medical, military and automotive electronics may still require the use of lead in electrode coatings.
To clarify the situation and distinguish products from each other, a special symbol is used on the packaging labels for RoHS compatible
capacitors.
Because of customer requirements, there may appear additional markings such as LF = Lead Free or LFW = Lead Free Wires on the
label.
