Cautions and warnings
Mechanical stress and mounting
Ferrite cores have to meet mechanical requirements during assembling and for a growing number
of applications. Since ferrites are ceramic materials one has to be aware of their special behavior
under mechanical load.
Just like any ceramic material, ferrite cores are brittle and sensitive to any shock, fast changing or
tensile load. Especially fast cooling rates under ultrasonic cleaning, high static and cyclic loads can
cause cracks or failure of the ferrite cores.
For detailed information see Data Book 2007, chapter "General - Definitions, 8.1".
Effects of core combination on AL value
Stresses in the core affect not only the mechanical but also the magnetic properties. It is apparent
that the initial permeability is dependent on the stress state of the core. The higher the stresses are
in the core, the lower the value for the initial permeability. Thus, the embedding medium should offer
the greatest possible elasticity.
For detailed information see Data Book 2007, chapter "General - Definitions, 8.2".
Heating up
Ferrites can run hot during operation at higher flux densities and higher frequencies.
NiZn-materials
The magnetic properties of NiZn-materials can change irreversibly when exposed to strong
magnetic fields.
Processing notes
– The start of the winding process should be soft. Otherwise, the flanges may be destroyed.
– Excessive winding forces may damage the flanges or squeeze the tube so that the cores can no
longer be mounted.
– Excessive soldering time at high temperature (>300 °C) may affect coplanarity or pin
arrangement.
– Not following the processing notes for soldering of the J-leg terminals may cause solderability
problems at the transformer because of contamination with tin oxide (SnO) from the tin bath or
burned insulation from the wire. For detailed information see Data Book 2007, chapter
"Processing notes, 2.2".
– The dimensions of the pin hole arrangement are fixed and should be understood as an ideal
recommendation for drilling the printed circuit board. In order to avoid problems when mounting
the transformer, customers should make allowances for manufacturing tolerances in the drilling
and pick-and-place processes by increasing the diameter of the pin holes.

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 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 an 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 an 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. The aforementioned does not apply in the case of individual agreements deviating
from the foregoing for customer-specific products.
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, BAOKE, Alu-X, CeraDiode, CSMP, CSSP, CTVS, DSSP, MiniBlue,
