Toroids (ring cores)
Toroids (ring cores)
General information
Our product line includes a wide range of toroids with finely graded diameters ranging from 2.5 to
202 mm.
Other core heights can be supplied on request. All cores are available in the usual materials.
1 Applications
Toroids are primarily used as EMC chokes for suppressing RF interference in the MHZ region
and in signal transformers.
Typical applications for toroids of NiZn ferrites are LAN chokes. One of the materials available
for this purpose is K10; other materials on request.
The following high-permeability MnZn materials are available for interference suppression:
R 2.5 through R 12.5 for telecommunications (N30, T38, T46)
R 13.3 through R 26 for power line chokes (N30, T65, T35, T37, T38)
>R 34 for chokes and filters in industrial use (T65)
Toroids are also increasingly used for power applications. Here, the typical values for amplitude
permeability and power loss, as summarized in the section on SIFERRIT Materials(page 36),
are applicable to the special power materials.
2Coating
Toroids are available in different coating versions, thus offering the appropriate solution for every
application. The coating not only offers protection for the edges but also provides an insulation func-
tion.
For small ring cores, we have introduced a parylene coating which features a low coating thickness
and high dielectric strength.
A coating of the core will cause μi to drop, depending on the core size. A similar effect might occur
when the core is subjected to high winding forces, especially cores made of the high permeability
materials, T38 and T46.

4Chamfer
Large toroidal cores use thick wires that are partially subjected to high mechanical stress during
winding. This can damage the wire insulation as well as the coating of the cores, thus reducing the
breakdown voltage. To avoid this, EPCOS toroids have a chamfer. This prevents any insulation
damage, and produces uniform coating thickness at the same time.
5 Cutting
Middle size and large toroids are available with gap:
1.) Cut into 2 halves with typical cuting wheel 2.) Cut gap in required thickness.
thickness 1.2 mm.
Three basic questions have to be answered during order:
toroid cuts into 2 halves/only gap (picture 1 or 2)
cutting before/after coating
before: air gap is coated
after: air gap is not coated, a measurement fixture can be placed into the air gap

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 tempera-
ture 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 data book, 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 is the value for the initial permeability. Thus the embedding medium should
have the greatest possible elasticity.
For detailed information see data book, chapter “General - Definitions, 8.1”.
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.
Ferrite Accessories
EPCOS ferrite accessories have been designed and evaluated only in combination with EPCOS
ferrite cores. EPCOS explicitly points out that EPCOS ferrite accessories or EPCOS ferrite cores
may not be compatible with those of other manufacturers. Any such combination requires prior te-
sting by the customer and will be at the customer‘s own risk.
EPCOS assumes no warranty or reliability for the combination of EPCOS ferrite accessories with
cores and other accessories from any other manufacturer.
Processing remarks
The start of the winding process should be soft. Else the flanges may be destroyed.
Too strong winding forces may blast the flanges or squeeze the tube that the cores can not be
mounted any more.
Too long soldering time at high temperature (>300 °C) may effect coplanarity or pin arrange-
ment.
Not following the processing notes for soldering of the J-leg terminals may cause solderability
problems at the transformer because of pollution with Sn oxyde of the tin bath or burned insula-
tion of the wire. For detailed information see chapter “Processing notes”, section 2.2.
The dimensions of the hole arrangement have fixed values and should be understood as
a 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.

Display of ordering codes for EPCOS products
The ordering code for one and the same product can be represented differently in data sheets,
data books, other publications and the website of EPCOS, or in order-related documents such as
shipping notes, order confirmations and product labels. The varying representations of the
ordering codes are due to different processes employed and do not affect the
specifications of the respective products. Detailed information can be found on the Internet
under www.epcos.com/orderingcodes.

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 require-
ments that are often placed on our products in the areas of application concerned. We never-
theless 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, EP-
COS 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 spec-
ification is suitable for use in a particular customer application.
2. We also point out that in individual cases, a malfunction of electronic components or fail-
ure 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 mal-
function or failure of an electronic component could endanger human life or health (e.g. in acci-
dent prevention or life-saving systems), it must therefore be ensured by means of suitable de-
sign of the customer application or other action taken by the customer (e.g. installation of pro-
tective 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 pub-
lication may contain substances subject to restrictions in certain jurisdictions (e.g. be-
cause 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. Consequent-
ly, 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”
