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 the special behavior

under mechanical load.

As valid for any ceramic material, ferrite cores are brittle and sensitive to any shock, fast changing

or tensile load. Especially high cooling rates under ultrasonic cleaning and high static or cyclic

loads can cause cracks or failure of the ferrite cores.

For detailed information see chapter “Definitions”, section 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 is the value for the initial permeability. Thus the embedding medium

should have the greatest possible elasticity.

For detailed information see chapter “Definitions”, section 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 irreversible in high magnetic fields.

Processing notes

– The start of the winding process should be soft. Else the flanges may be destroid.

– To strong winding forces may blast the flanges or squeeze the tube that the cores can no more

be mount.

– To long soldering time at high temperature (>300 °C) may effect 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 pollution with Sn oxyd of the tin bath or burned

insulation of the wire. For detailed information see chapter “Processing notes”, section 8.2.

– The dimensions of the hole arrangement have fixed values and should be understood asa

recommendation for drilling the printed circuit board. For dimensioning the pins, the group of

holes can only be seen under certain conditions, as they fit into the given hole arrangement.

To avoid problems when mounting the transformer, the manufacturing tolerances for

positioning the customers’ drilling process must be considered by increasing the hole diameter.

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 lifesaving 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).
