Hi,
Basically i'm building a dc-dc boost converter. With the switch switching at 20kHz.
I have calculated the component values and need a 6.8mH inductor with a saturation surrent of 5.5A or higher.
I have found this.....
https://cpc.farnell.com/jsp/Compone...playProduct.jsp?sku=TF00265&_requestid=344363
which seems to do just the job, but it doesn't say anywhere what material the core is made of, wouldn't an iron core become lossy at the frequency i want to switch at? been told i need a ferrite or ceramic core inductor....
having trouble finding inductors that can handle this current, can anyone recommend a site supplying them?
Thanks
