LL1583 Small Size Splitting Transformer

In many splitting applications, the splitting transformer must have a high immunity to input common mode signals, to
stray magnetic fields from e.g. power transformers and to large ground potential differences in receiving systems.
In the design of the LL1583, we have used our well established two coil structure to create a transformer with a high
degree of symmetry. The transformer is built up from two primary windings (which should be used in parallel) and two
secondary windings. Each secondary winding is built up from two sections, one from each coil. Its own electrostatic
shields surround each secondary section. The symmetric structure results in an internal cancellation of noise signals
caused by external magnetic field. It also increases immunity to ground noise between secondary systems and reduces
the effects of input common mode signals.
The transformer is housed in a mu-metal can and is impregnated in solventless epoxy resin.
