The shape of E cores is derived from
the classical iron sheet lamination
cores. For the original E range in fact
the dimensions of the existing lamination
range were taken so that already
commercially available coil formers and
mounting hardware could be used. The
former EF range has been optimized
for the use of ferrite as a core material.
Cross sections were rearranged
resulting in a homogenious magnetic
fl ux density in the core and more ***ce
for the windings. Main use is as power
transformer or choke in SMPS. E cores
have a simple shape and can therefore
be produced more economically than
more complicated cores.
A drawback is the rectangular crosssection
of the centre pole which makes
it more diffi cult to wind, especially with
heavy wires. Also the structure of the
core is rather open resulting in stray
fl ux sometines causing interference
problems. |
