Derating Recommendations, maximum continuous voltage
The maximum continuous voltage Vcont is the maximum permissible voltage at which the capacitor
can be continuously operated. It is a direct current voltage, or the sum of the basic DC voltage
plus the peak value of the superimposed AC voltage (see www.epcos.com/tantalum_gti, section
7).
The maximum continuous voltage depends on the ambient temperature (see figure below). Within
the temperature range of -55 °C to +85 °C, the rated voltage is equal to the maximum continuous
voltage.
In the temperature range between +85 and 105 °C the maximum continuous voltage must be
reduced linearily from the rated voltage to 4/5 of the rated voltage (Derating). Operation below the
maximum continuous voltage has a positive effect on the capacitor´s reliability.

voltage) versus temperature

Temperature dependence of the capacitance
The capacitance of an electrolytic capacitor varies with the temperature (positive temperature
coefficient). The amount by which it varies depends on the specific voltage and capacitance
value.

Dissipation factor
The dissipation factor tan δ increases with frequency and tends to very high values at
near-resonance frequencies. The figures below show the typical behaviour of the dissipation
factor.

Leakage current
When a direct voltage is applied to electrolytic capacitors, a low, constant current will flow through
any capacitor. This so-called leakage current Ilk is a function of the voltage as well as of the
temperature. (Graphs are shown below).
The absolute value of the leakage current of an electrolytic capacitor is determined by defects of
the dieletric. The (exclusive) usage of high-purity tantalum powder as raw material results in a low
total amount of defects and thus in a low leakage current level.

Storage conditions
EPCOS polymer capacitors are shipped in moisture barrier bags together with a desiccant and a
moisture indicator card.
All series (B760, B761, B763) are classified according JEDEC J-STD-020C as MSL 3 (Moisture
Sensitivity Level 3). Parts should be mounted 168 hours (= 7 days) after opening the moisture
barrier bags to prevent absorption of moisture and outgassing effects during soldering. Following
rules should be adhered to:
Parts must be stored in the reel and sealed moisture barrier bag until usage.
Parts should not be stored at high temperature, high humidity, corrosive atmospheres and
exposed to direct sun light. To enable the floor life of 168 hours according JEDEC J-STD-033A
a maximum temperature of 30 °C at a humidity of maximum 60% R.H. is required.
Temperature fluctuation should be minimized.
Environmental comments and warnings
As a manufacturer of passive components, we develop our products on the basis of the relevant
standards and laws, and thus ensure that our products are free of those materials and
substances prohibited by the relevant legislation.
To ensure a standardized procedure for EPCOS worldwide, a binding list of materials and
substances is included in our environment management system to ISO 14001. Our planning and
development guidelines include regulations and directives aiming to promote recognition of
environmental aspects and to optimize products and processes in terms of material use and
environmental compatibility, to design them with a sparing use of resources and to replace
hazardous substances as far as possible.
The environmental officer provides support in assessing the environmental risks of a
development project upon request. Consideration of environmental aspects is checked and
recorded at the design reviews.

Cautions and warnings
When using TOPcap capacitors, the following cautions and warnings should be taken into
account:
Polarity
Because polymer capacitors are polar capacitors, it is important to observe their polarity markings
(positive pole on the anode, negative pole on the cathode). Any incorrect polarity resulting from
the sum of the AC and DC voltage components must be smaller than or equal to the permitted
polarity reversal voltage (see “General technical information”, section 4.6 and section 4.8 under
www.epcos.com/tantalum_capacitors). To avoid reducing their reliability, this voltage may only
occur for a short time, at most five times for a total duration of one minute per hour.
Voltage
The maximum continuous voltage depends on the ambient temperature. Within the temperature
range of -55 to +85 °C, the rated voltage is equal to the maximum continuous voltage. Between +
85 and + 105 °C the maximum continuous voltage must be reduced linearly from the full rated
voltage to 4/5 of it (derating at 105 °C). Operation below the maximum continuous voltage has a
positive effect on the capacitor’s life time reliability. The maximum continuous voltage must not be
exceeded (see“Quality and environment”, section 1.11 under
www.epcos.com/tantalum_capacitors).
All unfavourable operating conditions (such as possible line overvoltages, unfavourable
tolerances of the transformation ratio of the line transformer in the equipment, repeated
overvoltages when the equipment is switched on/off, high ambient temperatures) must be taken
into account when determining the operating voltage.
The surge voltage is the maximum voltage (peak value) that may be applied to the capacitor for
short periods, at most five times for a total duration of up to 1 minute per hour (high
charge/discharge current comditions are not allowed above rated voltage). The surge voltage
must not be applied for periodic charging and discharging in the course of normal operation and
cannot be part of the operating voltage. The permissible surge voltage for all capacitors in this
data book is 1.3 x the rated voltage up to 85 °C (4/5 of the rated voltage for 85 °C up to 105 °C).
The occurrence of voltage impulses (transient voltages) that exceed the surge voltage may lead
to irreparable damage.
Capacitance
The actual capacitance of a capacitor can deviate from the rated capacitance by as much as the
full magnitude of the tolerance at delivery. Capacitance generally varies with temperature (at +85
°C up to +20%) and frequency (see “General technical information”, section 5 under
www.epcos.com/tantalum_capacitors).

Low-resistance applications and voltage networks
For low-resistance applications, EPCOS recommends a maximum operating voltage of half the
permissible maximum continuous voltage, so that the capacitors have sufficient tolerance to
withstand voltage peaks. Depending on the conditions of use, the early failure rate is maybe
higher here by a factor of 2 to 20 than in the range with a constant failure rate as specified in the
data book (see“Quality and environment”, section 1.11 under
www.epcos.com/tantalum_capacitors).
When operated directly in a voltage network, the capacitor should be protected against
overvoltage, e.g. by a suppressor diode, and against polarity reversal by a diode. If a capacitor is
operated in an unprotected low-impedance circuit and fails because the permissible conditions for
the forward DC voltage, reverse DC voltage, power dissipation or temperature are exceeded, the
continued current flow through the overstressed capacitor may produce overheating. The
overheated capacitor may damage the surrounding components and the circuit board
(see“Quality and environment”, section 1.11 and “General technical information”, section 4.11
under www.epcos.com/tantalum_capacitors).
Note
For more detailed information about cautions and warnings for tantalum electrolytic capacitors
(e.g. other electrical values beside those listed above),see “General technical information” and
“Quality and environment” under www.epcos.com/tantalum_capacitors.

Important notes
The following applies to all products named in this publication:
1. Some parts of this publication contain statements about the suitability of our products for
certain areas of application. These statements are based on our knowledge of typical requirements that are often placed on our products in the areas of application concerned. We
nevertheless expressly point out that such statements cannot be regarded as binding
statements about the suitability of our products for a particular customer application.
As a rule, EPCOS is either unfamiliar with individual customer applications or less familiar
with them than the customers themselves. For these reasons, it is always ultimately incumbent on the customer to check and decide whether an EPCOS product with the properties described in the product specification is suitable for use in a particular customer application.
2. We also point out that in individual cases, a malfunction of passive electronic components or failure before the end of their usual service life cannot be completely ruled out
in the current state of the art, even if they are operated as specified. In customer applications requiring a very high level of operational safety and especially in customer applications
in which the malfunction or failure of a passive electronic component could endanger human
life or health (e.g. in accident prevention or life-saving systems), it must therefore be ensured
by means of suitable design of the customer application or other action taken by the customer
(e.g. installation of protective circuitry or redundancy) that no injury or damage is sustained by
third parties in the event of malfunction or failure of a passive electronic component.
3. The warnings, cautions and product-specific notes must be observed.
4. In order to satisfy certain technical requirements, some of the products described in this
publication may contain substances subject to restrictions in certain jurisdictions (e.g.
because they are classed as “hazardous”). Useful information on this will be found in our
Material Data Sheets on the Internet (www.epcos.com/material). Should you have any more
detailed questions, please contact our sales offices.
5. We constantly strive to improve our products. Consequently, the products described in this
publication may change from time to time. The same is true of the corresponding product
specifications. Please check therefore to what extent product descriptions and specifications
contained in this publication are still applicable before or when you place an order.
We also reserve the right to discontinue production and delivery of products. Consequently, we cannot guarantee that all products named in this publication will always be
available.
6. Unless otherwise agreed in individual contracts, all orders are subject to the current version of the “General Terms of Delivery for Products and Services in the Electrical Industry” published by the German Electrical and Electronics Industry Association
