Characteristics
General
The advent of high-speed 56kBit modems has necessitated
the design of Line Isolation Transformers that are capable of
providing extremely low distortion across a wide frequency range.
OEP offers the user a number of different variants, with industry
standard pin outs, from which to select a device to satisfy
particular technical and commercial considerations.
Construction
With the exception of the SMD PC Card device, P/N PC3456
these transformers are designed for conventional PCB mounting.
The epoxy resin encapsulation provides reinforced insulation to
meet the requirements of EN60950 / EN41003 and BABT
approvals. Double section bobbins are used except for the
Z1656/4 and PC3456 versions which are concentrically wound on
single section bobbins for closer coupling of the windings thus
providing extremely low leakage inductance figures.
