HP3616 Ferrite Core
Core materials are used to achieve high inductances in a compact manner and to keep the R DC low. In ferrite, the material is ceramic, electrically non-conductive and sintered, which naturally significantly reduces eddy current losses. This makes ferrite particularly suitable for clean, defined work at higher frequency components and in the low-signal range.
Due to the low coercive field strength of the material, a high-quality ferrite such as HP3616 is characterized by very low ground distortions around zero crossing and a precise, controlled effect. As a result, corrective elements and equalizer branches remain clear, stable and free from unnecessary unrest. At the same time, the high magnetic permeability of the ferrite material allows compact designs and low RDC values.
The limit lies in the saturation reserve: At high currents, ferrite can reach its load limit earlier than aronite or feron. The inductance then changes effectively under load, and the filter effect can tip over when level peaks occur — ferrite must therefore be carefully sized for bass applications.
When used correctly, ferrite provides very clear, precise reproduction with high detail. This is also important in parallel branches and correction circuits, because core-related effects can manifest as additional signal components at the loudspeaker.
Ferrite is therefore the material of choice for precision applications where defined performance, compactness, and small-signal purity are paramount. In short: Ferrite is the tool for precision – with clear design limitations at high currents.
- Ceramic, non-conductive core material → very low eddy current losses
- Very clean in small signals (HP3616: low background distortions)
- Compact design and lower RDC possible
- Ideal for equalizers, correctors and precise midrange branches
- Bass only with a suitable design, as the saturation reserve is more limited than with Aronit/Feron
