The ER core design is derived from the original E core and, like
ETD and EC cores, has a round centre pole and outer legs with a
radius to accomodate round coil formers.
These cores are mainly used for power transformers. The round
centre pole allows the use of thicker wires while the shorter turn
length keeps the copper losses low.
