Welcome to "In the Loop". This issue spotlights Magnetics expanded size range of AmoFlux Toroids, Sales Engineer Jacob Hughs' presentation "Advantages of Using Appropriate MAGNETICS Materials", the upcoming PCIM Europe 2014 and some new sizes in MPP, High Flux, and Kool Mu Toroids.

AmoFlux Toroids - Size Range Expanded

AmoFlux is a powder alloy distributed gap material that is ideal for power factor correction (PFC) and output chokes. This alloy starts with amorphous ribbon that is pulverized into powder and then pressed into a toroid.

What makes this amorphous powder core material unique is the combination of low core loss and high DC bias. These attributes make AmoFlux an excellent choice for computer, server, and industrial power supplies that require high current inductors with superior efficiency.

Magnetics has expanded the size range of 60� AmoFlux toroids. The new, larger sizes are 0088083A7 (40.62mm OD), 0088439A7 (47.86mm OD) and 0088192A7 (57.86mm OD).

Please see the Dimensions and Magnetic Data table below for the current list of sizes now available.

Advantages of Using Appropriate Magnetics' Materials

A carefully considered power inductor is often the key design element to achieve a small, efficient, and cost-effective converter. The designer has many choices in powder core materials and shapes, each offering trade-offs among loss performance, cost , size, and ease of winding. An understanding of the advantages and disadvantages involved is necessary for making good choices.

The goal is to determine which powder core material is best for the design..

Magnetics distributed air gap materials available are:

MPP

80% Ni-Fe composition
