## Description

10 FT37-43 Toroid Ferrite Core: desertcart.com: Industrial & Scientific

Review: Just what I needed - Smaller than I expected them to be and winding wire on them takes some time and patience. But they work well and impedance is exactly where I calculated it to be. Sturdy too. One dropped on the floor from my bench and it didn't shatter or chip.
Review: Toroid works, know your sizing before hand and don't be surprised it's small. - All 10 came in intact wrapped in tape and bubble wrap. They seem to be well and and solid, no issues winding a toroid into a filter.

## Questions & Answers

**Q: Are these genuine Fair-Rite 5943000201? Or some rando core?**
A: The ones I received seemed genuine, not sure how to tell as they don't label them but they worked for the QRP HF stuff I was doing.

### ⭐⭐⭐⭐ poor packaging
*by R***B on September 29, 2025*

These are good cores but they could be packaged better. One came chipped because they are just placed in a non padded bag when shipped.
