LUNDAHL LL1574 TRANSFORMER Digital audio impedance matching, PC mounting, 100/75 ohms

A range of transformers designed specifically for digital audio. All have a relatively large amorphous metal core, and thus have low copper resistance, high signal tolerance and low internal capacitance. All these designs must be protected from DC current. Pin diameters are 1.1mm, recommended PCB drill 1.5mm.
Full data and application notes for each type are available from the Lundahl website at www.lundahl.se, or from Canford Technical Support.
