Isolating transformer for S/PDIF

Isolating transformer for S/PDIF
WARNING: do not use this transformer for mains isolating, because its insulation is not capable of handling this. It is intended to prevent earth loops arising or undesired signals being applied to the input of an appliance. For instance, a tape recorder is to be linked to a sound card in a computer which has an S/PDIF (Sony/Philips Digital Interface Format); the computer is not connected to protective earth (which in the UK is next to impossible and certainly not advisable).
