Cautions and warnings

Mechanical stress and mounting

Ferrite cores have to meet mechanical requirements during assembly 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.

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, DeltaCap, DigiSiMic,
