I am no longer selling the larger toroids like FT240-43 OR T200-2. They cost too much for me to import from USA (my supplier Kits and Parts dot com). I suggest you can use the following available at Mouser Electronics (Canada):

I have smaller toroids in stock BUT..FOR THOSE WHO WISH THE LARGER ONES that I no longer sell – MOUSER (canada) seems to have some available that look to be the right fit and 43 mix. Their nr 623-5943003801 seems to be the right one for substitute for FT240-43. The Mouser nr 5943002701 looks to be good for substitute for the also popular FT140-43 and for FT240-31 use 2631803802 TRUST BUT VERIFY note: UPS is only $8 flat charge delivery.

I STILL HAVE – HUNDREDS of smaller toroids and balun cores ect — just email me earl@nettyelectronics.com and I can give you prices and availability — with the smaller cores — I can ship letter mail right across Canada for only $2.15

Right Now (noted: 6 Oct 2019) Iam still selling the smaller toroids that I have brought in to my shop (by the hundreds). Toroids such as T30-2, T50-6, FT37-43, FT50 series and many more.


I can send these smaller toroids (using padded envelope and letter mail) — right across Canada for as little as $2.15 per order.


Nowadays.. China is starting to sell toroids on ebay and I have not bought any from China. I hesitate to do so because of the poor quality electronics parts that I have purchased and tested that have come from China and Ebay purchases in particular.


I dont have the technology to properly and thoroughly test Powdered Iron or Ferrite products.

IF YOU WANT SOME SMALLER TOROIDS at reasonable cost and ones you know are good USA products.. Feel free to contact me:
