**
General Remarks **

**Hot-spot temperature**Θhs

Temperature zone inside of the capacitor at hottest spot. It has to be noted that,depending on the thermal power dissipation generated inside the capacitor,there is always a temperature difference between hotspot and surface. As the hotspot is usually not accessible for measurement, Θhs must be calculated based on the data stated in the catalogue or data sheet:

Θhs =Θ_{A} + Irms^{2}x ESR x** **Rth

Important: No thermal dissipation losses are admissible when operating a capacitor at an ambient temperature equal to the upper category temperature,i.e. Irms and Q shall be zero (operation at pure DC voltage) !

**Dielectric dissipation
factor tanδ****0**

Constant dissipation factor of the dielectric material for all capacitors
at their rated frequency.The typical loss factor of pp film is tanδ0 = 2 x 10^{-4}.

**Dissipation factor
tanδ**

Loss factor of the capacitor at sinusoidal ac voltage and applied frequency.It is calculated as follows:

tanδ (ƒ) = tanδ0 + Rs x 2πƒ x CN

**Series resistance Rs**

The sum of all ohmic resistances occurring inside the capacitor.

**Equivalent Series
Resistance ESR**

Represents the sum of all loss resistances occurring in the capacitor. It depends on frequency and is essential for the calculation of the capacitor’s total power losses.

ESR = Rs +tanδ0 /(2πƒ x CN)

**Thermal resistance Rth**

The thermal resistance indicates by how many degrees the capacitor temperature at the hot spot rises in relation to the dissipation losses.

**Maximum power loss Pmax**

Maximum permissible power dissipation for the capacitor’s operation.

Pmax =(Θhs –Θ_{A})/Rth

**Self inductance Ls**

WN =1/2CN× UN²

**Clearance in air L**

**Creepage distance K**

The shortest distance along an insulated surface between conducting parts of the terminals or between terminals and case. In this catalogue, again we state only the shorter.

**AC capacitor Lifetime statements vs. Failure rate**

In the lifetime expectancy graphic, statements for more than 200,000 hrs are cut off as they are technically unreasonable. For higher hotspot temperatures, no statements are made regarding operation at overvoltage: the simultaneous operation at limit values results in unpredictable conditions. Here, the statement of a FIT rate - that reflects the growing risk at such extreme conditions - would be of far better use.

**AC capacitor Lifetime Expectancy Graphs**

**AC capacitor FIT rates
(Failures In Time):**

By reflecting the probability (in other words: risk) of failures during the operating period under selected operating conditions, it provides information on what effects to expect when de-rating (or over-loading) a capacitor. The failure probability of a component is a statistical value which is described by a log-normal distribution:

N = No × e^{¯λt}

N = number of functional components after period t

No = total number of components at time t = 0

λ = failure rate

λ is the failure rate, which alternatively is also stated as the so-called FIT-rate (FIT = Failures In Time = λ×10^{9}). Service cycles may be calculated based on the so-called MTBF value (mean time between failures): MTBF = 1/λ. The failure rate is very closely linked with the operating temperature and the operating voltage applied to the capacitor. As standard, our FIT rates are related to a realistic (from a technical and statistical point of view) operating interval of t=100,000 hours, assuming a capacitor hotspot temperature of60°C. Hotspot is the only reliable criterion in relation to the capacitor’s temperature stress. The outside temperatures may be comparably low, however with high electrical stress the temperature rise in the capacitor may be substantial due to the power dissipation losses produced inside. This could result in the same temperature stress as a generally high ambient temperature.

The simultaneous operation of capacitors at highest permissible voltage and operating temperature should be avoided; otherwise, failure rates may increase beyond reasonable technical reliability.

In fact, a FIT rate of 50 would mean, for example: “If 10,000 capacitors are operated simultaneously for 100,000 hours at rated voltage and with a hotspot temperature of no more than60°C, then out of this batch no more than 100 pcs may fail during the entire period.” Any period during which the hotspot temperature is lower than60°C, or the voltage is less than rated voltage, will contribute to a reduction of the 100 FIT.

After the reference interval, the capacitors will continue operating;
however the probability of failures may change. It shall be noted that the
statements on FIT rates are based mainly on long-year empirical experience; at **ADSO**, we are conducting numerous and
regular reliability tests to verify and back up our empirical knowledge.
However dedicated studies designed to prove FIT rates would require the test of
thousands of capacitors, over hundreds of thousands of hours, which is
technically and commercially impossible. Even the use of statistical methods and
accelerated ageing factors encounters physical and chemical limits.

Hence lifetime formulas such as

Lifetime (U) = LN x
(Urated/Uworking)^{8} and Lifetime (Θ) = LN x 2^{(}^{Θ}^{rated-}^{Θ}^{working)/7}

should not be used to calculate absolute figures of expected lifetime. These rules and formulas are mainly designed to give an approximate feeling for the importance of voltage and temperature.

All standard items of **ADSO** are designed
and dimensioned to comply with their FIT rate as stated in the catalogue or
special data sheet. FIT rate statements related to longer reference intervals
can be made on request. Further, capacitor designs can be adapted on request to
achieve lower FIT at the intended operating conditions.

Based on our current state of knowledge derived from test data and experience, we quote the following FIT rates for our standard products at the a.m. conditions:
