Inductance Factor Constrained Power Core Comparison

Choosing a ferrite for use as a power material is easy right? Pick the lowest loss material at your operating conditions and you’re off to the races. Unfortunately, it isn’t always that simple. In this video we take a look (simplistically) at how adding an air gap can affect our core material selection. Specifically, we are evaluating EQ25 core sets in Fair-Rite’s 67, 80, and 79 materials. All core scenarios have been constrained to roughly the same inductance factor for this testing.

Design Considerations for High Frequency Magnetic Materials Presentation

 In a developing market where miniaturization of designs has become critical, operating frequencies of magnetics have been increasing in order to minimize their size. As a result, engineers have a lot to consider when selecting magnetic components for their designs. Join us with John Lynch, Director of Engineering at Fair-Rite, as he discusses the role of ferrites in power supplies. John’s presentation will address the advantages of ferrites in power supply designs, the important parameters of ferrite materials, the impact of these parameters on performance, guidelines to select your ferrite material, and optimizing configuration based on design limitations.

Maintaining Impedance in Split Core Ferrites for Low Frequency Applications Presentation

Ferrites are ceramic components that can be used to suppress electromagnetic interference (EMI) in certain applications. This presentation will discuss the basic properties of solid round ferrite cores, the impact an air-gap can have on the performance of these cores, and special considerations. In particular, this discussion focuses on the use of high permeability materials, such as Fair-Rite’s 75, in low-frequency suppression applications since its permeability is relatively high compared to other soft ferrites used for this purpose, making the effect of an air-gap much greater.
