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.

All speciﬁcations typical at T_A=25°C

TECHNICAL NOTES

ISOLATION VOLTAGE

REPEATED HIGH-VOLTAGE ISOLATION TESTING

‘Hi Pot Test’, ‘Flash Tested’, ‘Withstand Voltage’, ‘Proof Volt-

age’, ‘Dielectric Withstand Voltage’ & ‘Isolation Test Voltage’ testing of a barrier component can actually degrade

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

isolation capability, to a lesser or greater degree

depending on materials, construction and environ-

ment. 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 de-

pend 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 there-

fore 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 opera-

tion?”

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 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 volt-

age 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 cor-

rectly 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-acces-

sible circuitry according to safety standard requirements.

For recommended alternatives please refer to the

DA100J Series datasheet.

This consideration equally applies to agency recog-

nized parts rated for better than functional isolation

where the wire enamel insulation is always supple-

mented by a further insulation system of physical

spacing or barriers.
