A fundamental concept to understand when using ferrites in a suppression application is the mode of the noise that is to be suppressed. In this video, we go over common and differential mode EMI and how ferrites can be used to attenuate them.

Ferrite rods and bobbins make excellent cores for a variety of different applications. These can range from wireless antenna cores (wireless power, Bluetooth, RFID, etc..) to high bias/power inductors, to chokes and many more. In this video we take a brief look at characteristics of the different core types and how they compare to one another.

Here at Fair-Rite Products, We pride ourselves on making all of our cores to an extremely high standard of quality. But, what happens when the best is isn’t quite enough? In this video we take a look some the specialized testing and processes used to ensure reliable operation no matter the application. At Fair-Rite; We’ll go the extra mile so you can go the extra million.
Follow along with Fair-Rite Products’ Bruce Sparrow , Product Manager for Suppression Applications, as he explains how different beads work to suppress EMI noise. With an assortment of materials to suppress frequencies from 100 kHz into the GHz range, Fair-Rite has the spectrum covered. You will quickly learn how to identify solutions to attain electromagnetic noise compliance. Watch and learn how Fair Rite Product Corp can be Your Signal Solution®.
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.

Fair-Rite Products Corp., Your Signal Solution®, In this video we give a brief example of the effect wire length has on rated impedance values of a ferrite EMI suppression device. When characterizing a core, the wire length should be kept to a minimum to give a more accurate representation of the of the actual impedance that will be added to your circuit.

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.
Fair-Rite Products Corp., Your Signal Solution®, introduces a roadmap of their 67, 79, and recently developed 80 materials. Be the first to join John Lynch, Director of Engineering at Fair-Rite, as he leads an informative presentation on the capabilities of the materials while also discussing the effects of size on their overall performance. The recently developed 80 material, in particular, is showcased in the video as the solution to the gap the 67 and 79 materials had previously left in frequency coverage. Fair-Rite is excited to share with you how these three products can empower your design. Please watch our video to learn more.
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.

This video discusses the basics of ferrite beads and their uses for basic filtering applications. It discusses and demonstrates how ferrites act as resistors at high frequencies and how this is used for EMI/RFI Suppression, improved power supply filtering, parasitic oscillation suppression, and others. The affect of the frequency dependent resistive characteristic of the ferrite beads is demonstrated by showing its effect on a swept RF signal, its effect on the rise/fall time of a digital signal, and its effectiveness of eliminating parasitic oscillation.
