FT-140-43 Ferrite Toroid Core - Amidon | 43 Material

Good quality toroids, I was working on a product and used these to prototype. They worked good. I have since moved on only because I can get them cheaper in bulk. But if I only needed one or 2 I would be happy to purchase these again.

I Ordered several of these for building Ham wire antennas, and they all have worked as they should. They were shipped quickly and packaged very well. I will purchase more when needed. The price was right and good value for the money.

Buy these for EFHW transformers. Made a portable 40m antenna i achieved under 1.3 SWR on 40, 20 15 and 10m.

The folks at FW Electronics are great. This was a product I needed and wanted. I ordered it and the product arrived quickly and painlessly. Nearly all the way good. I opened the packaging and noticed a discrepancy between what I ordered and what I received. Quickly a mistake was realized and communicated to FW-Electronics. Of course, these discrepancies can cause problems if you aren't careful. FW-Electronics sent a replacement just as quickly and without additional cost to me. For most everyone, these are the critical details. Product sold, good product, fast turnaround, etc. All of those things I report about FW - Electronics. Here's the important part of the review: This company made a mistake, initially. These things happen and nobody was upset. Understanding that toroid core mixes are very specific for use in amateur radio applications (as in other applications). So there's a confidence concern in my case when I lack the test equipment to identify the different mixes. FW - Electronics helped me visually identify the core types and sent the correct (though properly labeled) toroid cores without cost to me, and let me keep the incorrect toroids (which I still will readily put to good use at my QTH or to a deserving ham learning to use RF chokes). My point in this detail is I appreciate great products and great service. But I appreciate it so much more when things *don't* go well and the company and staff make it right. Nobody's perfect, but making it perfect when it isn't shows me the company appreciates the customers' work product and respects their own. I'll keep coming back to FW! 73 DE K6RCS

Works as advertised. Excellent condition no defects.. Used as a matching transformer in an EFHW antenna as the. Heart of a 49:1UNUN.
