In Reply to: Toroidal vs. Iron Core Isolation Transformer posted by Duster on June 29, 2004 at 17:54:58:
Toriods are WAY higher in capacitance, which allows the primary to couple with the secondary. As such, the higher the capacitive coupling, the less isolation that one achieves. Having said that, a good toroid will get you about -85 dB's and a good low capacitance iron core will be down about -145 dB's. This is not to mention that most high quality iron core's will have WAY more core material, reducing non-linear hysterisis distortions due to saturation.With far greater isolation, reductions in non-linear distortions, etc... why would anyone want to run a toroid? Only reasons that i can think of would be cost, convenience and weight, which are all factors when one is mass-producing a product. When it comes to actual performance for a DIY'er that is designing / building for themselves and can take all of the factors into consideration, there are no reasons to use a toroid. Sean
