New from Magnetics, XFlux Ultra powder cores offer the same great DC Bias and high saturation found in standard silicon-iron XFlux while providing a 20% improvement in core loss.

Historically, applications requiring a high DC Bias powder core with minimal temperature rise would resort to High Flux. Positioned with losses between standard XFlux and High Flux, XFlux Ultra can also meet this need at a fraction of the cost of nickel-iron High Flux.

Applications for XFlux Ultra may include high efficiency uninterruptible power supplies (UPS), high power SMPS, and power factor correction (PFC) for on-board chargers (OBC). 

Available in 26 and 60 permeabilities with OD dimension 13.5 mm to 135 mm. Contact Magnetics for more information.

Magnetics introduces two new sizes to their amorphous core product line - MACC0160 and MACC1000.

As a valued customer, we wanted to provide you with an update related to the COVID-19 "coronavirus".

Concerns about the coronavirus continue to rise. We are monitoring reports from the Centers for Disease Control (CDC) and have taken precautionary measures for the health and safety of our employees.

The provincial government of the Fujian province, where our factory is located, ordered a delay in the resumption of work from 3-10 February 2020 after the Chinese New Year. Since then, our factory has resumed work and is fully staffed. Currently we are not experiencing any delays in manufacturing or shipping from our factory in China.  We are closely monitoring port closures in countries we ship to.

Our US warehouse in Phoenix, AZ remains open. All order delivery dates are being met. Office staff are working from home, and we anticipate no interruption in our level of customer service.

If the situation should change, we will notify our customers as soon as possible.

Magnetics® now offers 125 permeability XFlux toroids, in addition to the existing 19, 26, 40, 60, 75, and 90 permeabilities. Currently available in two sizes - 27.7 mm and 33.7 mm. Contact us for your quotation and sample requests.

Magnetics introduces a breakthrough powder core material for minimum size and maximum efficiency - Edge^TM. 

Edge provides a dramatic improvement in DC bias performance over High Flux while also cutting AC core losses to less than half of High Flux losses. In fact, Edge is the highest DC bias powder core material currently available.

Edge is available in permeabilities of 26 and 60 and in standard toroid sizes up to 40 mm diameter, as well as custom heights. Larger cores and additional permeabilities, including 125µ, are in development for release later in 2020.

For more information, see our Edge technical bulletin.
 

Magnetics introduces an advanced Kool Mµ material for low losses at high frequency and superior efficiency - Kool Mµ® Hƒ.

Kool Mµ Hƒ was derived from the growing need for efficient power inductors in GaN and SiC power supplies. Although customer demand influenced a target operating range of 200-500 kHz, Kool Mµ Hƒ losses are dramatically improved at all frequencies. Kool Mµ Hƒ displays improved losses as high as 2-3 MHz for high efficiency inductors while matching MPP losses at traditional lower frequencies (20-200 kHz). Therefore, Kool Mµ Hƒ can be attractive for any high efficiency power supply design, not only those using GaN and SiC switching at high frequency.

Kool Mµ Hƒ is currently available in permeabilities of 26 and 60 and in standard toroid sizes up to 40 mm diameter. Additional permeabilities and larger cores are in development for release in late 2020. For more information, view our Kool Mµ Hƒ technical bulletin.
 

Magnetics has announced new 44 mm size toroidal cores available in High Flux, Kool Mµ, Kool Mµ MAX, MPP, and XFlux materials in multiple permeabilities. Dimensions of the epoxy-coated cores are 43.83 mm OD, 23.4 mm ID, and 17.26 mm HT.

This 44 mm size is optimal for adhering to height limitations of a 1.5 rack unit (2.625 in./66.675 mm).

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 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:

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

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.

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.

Magnetics updated XFLUX Cores Bulletin is now available in printed and pdf versions.  Magnetics’ XFLUX distributed air gap cores are made from 6.5% silicon iron powder and offer lower losses than powdered iron cores and superior DC bias performance.  The soft saturation of XFLUX material offers an advantage over ferrite cores.  XFLUX cores are ideal for low and medium frequency chokes when inductance at peak load is critical.

Now available: Toroids in 26µ and 60µ, E Cores in 26µ, 40µ and 60µ, Blocks in 26µ, 40µ and 60µ.

The catalog is available in pdf versions and as an e-catalog.

Magnetics' Hong Kong Distribution Center relocated to a new facility in early August. The new facility is located at Unit A on 5th Floor of Olympic Godown, No. 8 Sze Shan Street, Yau Tong, Kowloon, Hong Kong.

Magnetics is now shipping from this new location.

Magnetics appreciates your cooperation and patience in this transition.
