Iron-Core

I have been incorrectly calling Jantzens 'Iron-Core' inductors 'P-Core' inductors for many years.
The inductors I stock are all still the exact same inductors that I have always stocked.
The only change is I am now using the correct naming. I apologize for any confusion.

Below is an explanation of the differences between P-Core and Jantzens Iron-Core inductors.

P-core inductors refer to inductors made with a core from soft ferrite. A high-permeability ceramic compound.
These offer higher inductance and energy storage in a smaller size, making them ideal for filtering and power applications.
Ferrite cores will generally have a lower resistance figure compared to non-ferrite cores of the same mass and shape.
But will saturate earlier and have a much harder loss curve on inductance once the saturation point is reached.

Jantzens Iron-Cored inductors are made from non-ferrite pressed Somaloy® powder. A composition of powdered iron.
Non-ferrite inductors are often used in high-frequency, high-Q (high-quality factor) circuits where lower loss is critical and size is less of a concern.

Cored inductors exhibit lower DCR when compared to air cored coils of the same wire gauge.
The benefits of which include the preservation of amplifier damping as well as overall speaker sensitivity.

Although we try to keep a reasonable variety of inductors in stock, there might be the odd occasion when we don't have exactly what your after.
If you find yourself in this situation, Please contact us as we have the facilities to unwind a higher value inductor to your needs.
This free service is for those that only require a few inductors altered.

For commercial quantities, we will order the value and quantity that you require from Jantzen.
