R core transformer

What's an R-Core?

R-Core is a compact and low profile core that can be used in place of E-I or Toroidal transformer.  The shape resembling that of a race track has two balanced windings on either side for reduction of EMF.

What are the advantages of using an R-Core?

- Lower profile and smaller size.

- Lower stray EM field from the round cross-sectional area and the balanced windings on either side.

- Lower core losses from no cuts the in core and minimized distance between the core and the windings.

- Lower temperature rise and noise form the round cross-sectional area and tappered slitting.

- Impressive modern appearance.

What sizes are R-Cores manufactured to?
