Tantalum chip capacitors

Cautions and warnings
When using tantalum capacitors with a manganese dioxide coating, the following cautions and
warnings should be taken into account:
Polarity
Because tantalum 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 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 + 125 °C the maximum continuous voltage must be reduced linearly from the full rated
voltage to 2/3 of it (derating). At 150 °C (only B4519*P series) the voltage must be reduced to 1/2
and at 175 °C (only B4519*T series) to 1/3 of the rated voltage. Operation below the maximum
continuous voltage has a positive effect on the capacitor’s failure rate. 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, 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. 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. 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. The capacitance varies with the temperature (at
+125 °C +12% up to +20%) and decreases with increasing 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 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, surge current, 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).
Storage conditions
Capacitors with solid electrolyte may be stored at temperatures down to –80 °C. The upper
storage temperature must not exceed +85 °C (for blister tape the temperature limit is +40 °C).
The storage conditions should not exceed +40 °C and 70% R. H. A drypack is useful to prevent
the effects of humidity.
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
(ZVEI).
7. The trade names EPCOS, EPCOS-JONES, Baoke, CeraDiode, CSSP, MLSC, PhaseCap,
PhaseMod, SIFI, SIKOREL, SilverCap, SIMID, SIOV, SIP5D, SIP5K, UltraCap, WindCap are
trademarks registered or pending in Europe and in other countries. Further information will
be found on the Internet at www.epcos.com/trademarks.
