where can one buy a bag of ferrites?
- urlgrey 3y agoThere are several options from Amazon, try searching for "Clip-on Ferrite Ring".
- genewitch 3y agoI know; i hoped for a site that sells all the types of rings, binocular, clip-on - which are great for choking VHF vertical dipoles with the bottom leg being spokes that are obviously too short for the frequency - i digress. I'm also just grown weary of amazon.

- wglb 3y agoCheck out https://proaudioeng.com/fair-rite-ferrites/ https://proaudioeng.com/fair-rite-ferrites/. Also dxengineering has them.
- genewitch 3y agoType 31: > Mix 31 excellent for 1-10 MHz common mode suppression, then about same as 43 up to 250 MHz, NOT recommended for multi-ratio impedance transformers (baluns/ununs) due to material characteristics and power handling capability – ok for ham radio 1:1 feed line choke applications. Curie temperature >130 C But in looking for concise relevant information i found https://palomar-engineers.com/ferrite-products/ferrite-cores/ferrite-mix-selection https://palomar-engineers.com/ferrite-products/ferrite-cores... which i quoted above edit: also, thank you
- gorkish 3y agoAnother way to get a lot of ferrite cores for super cheap is to harvest them from cables that included them like VGA and DVI cables. you can cut them out and peel off the overmolding. Most are still split core. The material is often not very good at lower frequencies like HF, but you can use more cores or loop your cable through multiple times to increase the effectiveness of the choke.
