AES - DATS conversion transformer LL1574

LL1574 is a pulse transformer designed for impedance matching between 110 ? and 75 ? systems. The transformer has a large amorphous metal core which results in low copper resistance, high signal tolerance and low internal capacitance.

Turns ratio: 1 : 1.2
Impedance ratio 75 : 110
Dims: (Length x Width x Height above PCB (mm)) 15 x 9 x 11

Spacing between pins: 5.08 mm (0.2")
Spacing between rows of pins: 10.16 mm (0.4")
Rec. PCB hole diameter: 1.5 mm
Weight 2 grams
Core Amorphous core material
Static resistance of primary (Pins 1 - 2): 1.0 ?
Static resistance of secondary(Pins 3 - 4): 1.1 ?
Maximum primary signal time before saturation: 160 Vs at 8 volts p-p.
Maximum no load current at above conditions: ? = 3 mA
Primary main inductance (tuned at 10 kHz, 2 V): 40mH
Primary leakage inductance: 1.3 H
Total coupling capacitance: < 15 pF
Winding capacitance: < 1 pF
Isolation between windings: 2 kV
Source impedance: 0 -- 500 ?
Optimum load impedance: 200 ?
