[RFI] List of ferrite sources and prices

Tue Sep 29 00:15:07 EDT 2020

Here’s a price and stock survey on ferrite toroids and clamp-ons for ham RFI applications. I post this occasionally. Some of the entries were updated a couple months ago, others are older. Stock status fluctuates... Anyway, this will give you a general comparison of prices and plenty of alternate sources to check. And you’ll quickly see why Palomar Engineers is the last place you want to go when buying ferrite.

————————————-

Showing only suppliers with websites that list inventory and allow online ordering. When ordering 2.4-inch toroids, order in multiples of 10, then most suppliers will pack them in original factory-molded foam sheets.

Call these companies for quotes. Prices in larger quantities often beat anything listed here.
