Lundahl Digital Audio transformer, LL1573

Digital audio transformers LL1573 (1:1:1)

The LL1572, LL1573, LL1589 are pulse transformer designed for digital audio. They are designed with a rather large amorphous metal core and have thus low copper resistance, high signal tolerance and low internal capacitance. The amorphous core has a very high mu. Thus, when used, the transformer should be protected from DC current.
