Hi All.
In February, we will be publishing an Essentials of Ferrites.
We wanted to do something a little different and add in a project (or it could be an experiment) with ferrites.
The sponsor is sending element14 three ferrites kits to hand out to anyone who is interested in doing this project. You can add in anything else you might think you need.
If you have any questions, feel free to leave a comment or message me.
Cheers.

Very nice kit!
They are great problem-solvers, getting rid of unwanted oscillations and suppressing noise. For anyone curious, for a certain frequency range, they act like a resistance (at a very high-level). There are different kinds of ferrites for different applications, but specifically, this is for those intended for "suppression", which is what this kit is for, i.e. designed to have high(ish) resistance at certain frequency ranges. Other ferrites may be intended for "inductive" applications, use-cases would include oscillators for instance.
It's sometimes easy to know because for companies like Wurth, they will provide nice detail: the red dashed line shows the resistance component at different frequencies. Many manufacturers won't provide such granular information, they may just mention the resistance at specific point frequencies.
I only have one ferrite kit for suppression, which is pretty ancient, and therefore so far have just been buying specific ferrites and this limits experimentation.
Wurth has many nice kits. I recently purchased a couple of Wurth inductor and capacitor kits. It's been a huge time-saver, having a range of parts on-hand. Great learning experience too, having the range of parts to experiment with.
Coilcraft has really neat inductor kits too (but the Wurth ones have a bigger selection!).
They end up being a lifetime supply since (I believe) Wurth and Coilcraft will replenish the kit forever (provided the kit is used fairly).
