Tibeliusgatan 7 International Domestic LUNDAHL S-761 50 NORRTALJE Phone +46 - 176 13930 0176-13930 TRANSFORMERS SWEDEN Fax +46 - 176 13935 0176-13935 Digital audio transformers LL1572 (1:1), LL1573 (1:1:1) and LL1589 (1:1:1:1) 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.
