Kool Mu MAX Powder Cores (3/27/2017)


New from Magnetics!
Kool Mµ® MAX is the next generation of sendust cores from Magnetics. We supercharged our low core loss Kool Mµ material with 50% better DC bias performance for better power handling. Use of copper wire is minimized by maintaining inductance using less turns, resulting in savings in overall component cost. With its super low losses, Kool Mμ MAX does not mimic the temperature rise problems found in iron powder cores. Improve inductor efficiency at a fraction of the cost of High Flux with Kool Mµ MAX.

Nylon Coating Discontinue (3/14/2017)

Beginning Q4 2017, Magnetics will be discontinuing the nylon coating process (V) for ferrite cores due to environmental compliance regulations beyond our control. Our recommended replacement for nylon coating is epoxy (Z) coating. If you require nylon coating, please contact Magnetics Customer Service no later than August 1, 2017 to place a last time buy purchase order for your required quantities. After August 1, we will only accept purchase orders for cores that consume unsold inventory.

Magnetics 95 mm Blocks (7/21/2016)

Magnetics’ 95 mm blocks are equivalent to two of our standard 47 mm blocks (00K4741BXXX). Ideal for high current inductors, large Kool Mu blocks enable creation of custom designs. Typical examples of uses for high current inductors are Uninterruptible Power Supply (including transformerless UPS), large PFC chokes, traction output filters and inverters for renewable energy (solar/wind/fuel cell conversion). A critical parameter of a switching regulator core material is its ability to provide inductance, or permeability, under DC Bias.

The biggest advantage of using large Powder Core blocks is in ease and time of production, with less room for error. With Powder Core blocks, a designer can build an inductor customized to fit the specific design constraints. As a benefit, assembly times are decreased because fewer blocks need to be glued together.

XFLUX® Blocks (4/27/2015)

Magnetics now has XFLUX Blocks available in 50x30 mm (00X5030Bxxx), 60x30 mm (00X6030Bxxx), 70x30 mm (00X7030Bxxx) and 80x30 mm (00X8030Bxxx) and in 26, 40 and 60 permeabilities.

XFLUX cores offer an economical high saturation (1.6 Tesla) solution for use in low and medium frequency inductors and chokes.  The high saturation is advantageous in applications where inductance uner load is critical such as inverters for renewable energy and Uninterruptable Power Supplies (UPS).

XFLUX distributed air gap cores are made from 6.5% silicon iron powder.  It is a  true high temperature material, with no thermal aging.  A comparison chart with other materials is below:

wPjTy6u5egs3AAAAABJRU5ErkJggg.png

Many applications require a custom assembly or even a custom core. The material properties of XFLUX®, and the flexibility of these geometries make the core ideal for custom assembly.

Assembly Considerations

XFLUX-Blocks-Quantity-of-8-B6030-Blocks.png

Discrete air gaps between XFLUX blocks are not generally needed because the air gap is inherent in the material. At the same time, extremely smooth mating surfaces (such as are employed with ferrites) are not required because the small incidental gap between blocks does not add appreciable extra gap and does not reduce inductance significantly.

The adhesives used for assembling blocks generally need to be thicker than those commonly used for ferrite assemblies, since the
XFLUX surface is rougher and more porous. Cores may require a double application of adhesive to allow for the porosity in the surface of the XFLUX blocks.

Large Kool Mµ E Cores (4/17/2015)

Magnetics now offers 80x24 (00K8024EXXX) and 80x44 mm (00K8044EXXX) Kool Mµ E cores in 14µ, 26µ, 40µ and 60µ.  Also available in 14µ, 26µ, 40µ and 60µ is the 114xXX mm E450 Kool Mµ E Core (00K114LEXXX). The E450 has 3.7 times greater overall volume than the E80.

Ideal for high current inductors, large Kool Mμ geometries offer all the advantages of Kool Mμ material, low core loss, excellent performance over temperature, near zero magnetostriction and soft saturation. Typical examples of high current inductors are Uninterruptible Power Supply (including transformerless UPS), large PFC chokes, traction and inverters for renewable energy (solar/wind/fuel cell conversion).  The most critical parameter of a switching regulator inductor material is its ability to provide inductance, or permeability, under DC bias. The distributed air gap of Kool Mμ results in a soft inductance versus DC Bias curve. In most applications, this swinging inductance is desirable since it improves efficiency, decreases the volume needed and accommodates a wide operating range. With a fixed current requirement, the soft inductance versus DC bias curve provides added protection against overload conditions.
