Ferrites are used not only in the known consumer and professional electronics applications, but also in science and industry. The specifications and tolerances required for scientific and industrial applications are generally very demanding and critical. Experts in ceramic technologies know that making territe is one thing, machining it to close tolerances is another.
Ferroxcube provides optimal materials for different operating conditions. Working temperature, flux and frequency are the key parameters to select the proper material: from standard 100 deg C to 60 in handheld converters or 140 in automotive, or even wide range 20 to 100 or 60 to 140.
Low core losses at working frequency and temperature to achieve high efficiency Switching at higher frequencies allows size and cost reduction of the magnetic components Low profile shapes are recommended to build compact and modular designs
The trend toward high power density, high operating frequency, and low profile in power converters has exposed a number of limitations in the use of conventional wirewound magnetic component structures. Transformers made of the planar principle eliminate virtually some shortcomings of old‐fashioned wire wound types, and thus planar magnetics, has in recent years, become increasingly popular in high frequency power converters.
The essence of the fluxgate principle is that the inductance of the easily saturated magnetic core changes with the magnitude of the excitation current under the action of the excitation current, and the change of the inductance leads to the change of the magnetic flux. The magnetic flux is opened or closed like a door, so it is visualized fluxgate Principle.

Have you ever pondered the significance of the mystical number 32768? Well, it all boils down to the utilization of a 32768Hz, or 32.768kHz, frequency for RTC/Timer purposes, which yields a precise 1-second delay. Remarkably, 32768 is a power of 2—specifically, 2 to the power of 15 equals 32768. Consequently, employing a 15-stage divider, we can effectively divide 32.768kHz into 1Hz, laying the foundation for achieving a 1-second period with ease.
The MultiGap concept is simple: instead of having one single large air gap in the center leg, the gap is distributed along the center leg by means of spacers along the leg length (up to seven smaller gaps). Reduce significantly the fringing Flux around them, allowing the coil to be much closer to the center leg and keeping the eddy current losses in the winding very low.
