FEATURES
J-STD-020D refl ow RoHS compliant Compatible with leading chip sets 2kVrms isolation Industry-standard pinout Surface mount option UL 94 V-0 package materials Low profi le Suitable for both 75 & 110Ω circuits Toroidal construction Compliant with AES/EBU standards
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. For through hole versions see DA100 series datasheet.

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?” For a part holding no specifi c 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. REPEATED HIGH-VOLTAGE ISOLATION TESTING 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 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 specifi ed test voltage. 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.
