DESCRIPTION
The Digital Audio Range of transformers is
designed to improve the balance of transmitter
and receiver circuitry in hi-fi equipment,
video games and other applications requiring
high-performance digital audio transmission.
Compliant with AES/EBU recommendations for the
digital audio interface, offering optimised shunt
capacitance between primary and secondary
windings. Capable of operating over the audio
data rate frequency range, providing isolation from
50-60Hz noise.
Surface-mount parts
The surface-mount (M suffix) products are not
recommended for new designs. For existing designs,
however, Murata Power Solutions will continue to
manufacture and fully support these parts.
For recommended alternatives please refer to the
DA100J Series datasheet.

TECHNICAL NOTES
ISOLATION VOLTAGE
REPEATED HIGH-VOLTAGE ISOLATION TESTING
‘Hi Pot Test’, ‘Flash Tested’, ‘Withstand Voltage’, ‘Proof Voltage’, ‘Dielectric Withstand Voltage’ & ‘Isolation Test Voltage’
are all terms that relate to the same thing, a test voltage,
applied for a specified time, across a component designed
to provide electrical isolation, to verify the integrity of that
isolation.
It is well known that repeated high-voltage isolation
testing of a barrier component can actually degrade
isolation capability, to a lesser or greater degree
depending on materials, construction and environment. This series has toroidal isolation transformers,
with no additional insulation between primary and
secondary windings of enameled wire. While parts
can be expected to withstand several times the
stated test voltage, the isolation capability does depend on the wire insulation. Any material, including
this enamel (typically polyurethane) is susceptible
to eventual chemical degradation when subject to
very high applied voltages thus implying that the
number of tests should be strictly limited. We therefore strongly advise against repeated high voltage
isolation testing, but if it is absolutely required, that
the voltage be reduced by 20% from specified test
voltage.
All products in this series are 100% production tested at
their stated isolation voltage.
A question commonly asked is, “What is the continuous
voltage that can be applied across the part in normal operation?”
For a part holding no specific agency approvals both input
and output should normally be maintained within SELV limits
i.e. less than 42.4V peak, or 60VDC. The isolation test voltage represents a measure of immunity to transient voltages
and the part should never be used as an element of a safety
isolation system. The part could be expected to function correctly with several hundred volts offset applied continuously
across the isolation barrier; but then the circuitry on both
sides of the barrier must be regarded as operating at an
unsafe voltage and further isolation/insulation systems must
form a barrier between these circuits and any user-accessible circuitry according to safety standard requirements.
This consideration equally applies to agency recognized parts rated for better than functional isolation
where the wire enamel insulation is always supplemented by a further insulation system of physical
spacing or barriers.
