Ring Cores
General Information
● Our product line includes a wide range of ring cores with finely graded diameters ranging from
2,5 to 200 mm (see overview of available types). Other core heights can be supplied on request.
All cores are available in the usual materials.
Ring cores 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 function.
The following test setup is used to test the dielectric strength of the insulating coating: A copper
ring is pressed to the top edge of the ring. It touches the ferrite ring at the edges (see diagram).
The test duration is 2 seconds; the test voltages specified in the table are minimum values for
epoxy- and Rilsan-coated cores:

For cores with high permeability, increased spread of the AL values of several percent must be expected according to the specifications due to the Polyamid coating process. This effect can be
avoided by using an epoxy resin coating (L version).
For small ring cores, we have introduced a parylene coating (Galxyl) which features a low coating
thickness and high dielectric strength.
● Ring cores are used primarily for pulse and broadband transformers, baluns and chokes. Owing
to the magnetically closed circuit, high flux densities can be achieved at small volume. Magnetic
leakage is negligible.
● Ring cores are also increasingly used for power applications. Here, the typical values for ampli-
tude permeability and power loss, as summarized in the section on SIFERRIT materials
(page 33), are applicable to the special power materials.
● Characteristic data for cores not included among the preferred types are available on request.

General Information
Application: Ring cores to suppress line interference
With the ever-increasing use of electrical and electronic equipment, it becomes increasingly important to be able to ensure that all facilities will operate simultaneously in the context of electromagnetic compatibility (EMC) without interfering with each others’ respective functions. The EMC legislation which came into force at the beginning of 1996 applies to all electrical and electronic products
marketed in the EU, both new and existing ones. So the latter may have to be modified so that they
are neither susceptible to electromagnetic interference, nor emit spurious radiation. Ferrite cores
are ideally suited for this purpose since they are able to suppress interference over a wide frequency range.
At frequencies above 1 MHz, ferrite rings slipped over a conductor lead to an increase in the impedance of this conductor. The real component of this impedance absorbs the interference energy.
A ferrite material´s suitability for suppressing interference within a specific frequency spectrum depends on its magnetic properties, which vary with frequency. Before the right material can be selected, the impedance lZl must be known as a function of frequency.
The curve of impedance as a function of frequency is characterized by the sharp increase in loss at
resonance frequency.
Measurement results:
The measurements shown here were made at room temperature (25 ± 3 ˚C) using an HP 4191A
RF impedance analyzer with a flux density of B ≤ 1 mT.
The maximum of the impedance curve shifts to lower frequencies as the number of turns increases;
this is due to the capacitive effect of the turns (figure 1, using R25/15 as an example).
Figure 1
For direct comparison of the typical suppression characteristics of differenct ferrite materials, the
impedance curves were normalized using the equation lZ l n = lZ l / N 2 x Σ (le / Ae); the geometry
factor was calculated on the basis of the core dimensions (figure 2).
These normalized impedance curves are guide values, mostly measured using ring core R 10 with
a number of turns N = 1 (wire diameter 0,7 mm); they may vary slightly, depending on the geometry.
