R-Core vs Toroid - diyAudio

Oct 06, 2004· EI (frame) core, C-core and R-core transformers usually have split-bobbin primary and secondary windings, which cuts down on interwinding capacitance and makes it considerably more difficult for non-50/60Hz noise components to pass in and out of the power supply.

Good question: Why DON"t we see R-core transformers in new ...

Jul 31, 2014· At any rate, I'd think that R-Cores would share the bane of toroids, the nearly perfect magnetic circuit that makes even the slightest DC offset saturate the coil, unless the core is slit, and slitting the core means using a lot bigger core. However, I do see ads for R-Core single ended output transformers, so there is a workaround somehow.

Why a Torroidal instead of an R-core Transformer in digital?

Sep 15, 2013· What you have stated is mostly true. However, the reason why R-core transformers are the best choice for ALL low level audio applications, is due to their far lower coupling. This means that any mains-bourn interference will be greatly attenuated by an R-core transformer, compared to a toroidal. E-I type transformers lie somewhere in the middle.

Air-core transformer. These are used for high frequency work. The lack of a core means very low inductance. All current excites current and induces secondary voltage which is proportional to the mutual inductance. Such transformers may be nothing more than a few turns of wire soldered onto a printed circuit board. Ferrite-core transformer
