The LL1545A transformer can be used in many different applications such as a high impedance line input transformer (accepting signal levels of 22 dBU @ 40 Hz with primaries in series), for splitting or as a microphone input transformer. The LL1545A is made with a mu-metal core and is housed in a mu-metal can. Refer to page 2 of this sheet for termination alternatives. Turns ratio: 1 + 1 + 1 + 1 : 2 + 2 Dimensions: (Length x Width x Height above PCB (mm)) Spacing between pins: 2.54 mm (0.1") Spacing between rows of pins: 22.86 mm (0.9") Weight: 46 g Rec. PCB hole diameter: 1.5 mm Static resistance of each primary (average): 147 O Static resistance of each secondary (average): 295 O Self resonance point: > 220 kHz Recommended load for best square-wave response (Termination alternative A below): 6 .7 k O+ 470 pF Frequency response ( source 600 O, load (6.7 k O+ 470 pF) in parallel with 56 k O): 10 Hz - 70 kHz +/- 0.5 dB @ 0 dBU Loss across transformer (at mid-band with termination as above): 0.3 dB Core: Mu-metal Isolation between windings / between windings and shields: 3 kV / 1.5 kV

Sehr gutes Produkt! Sehr gutes Produkt! Die Dokumentation der Beschaltung ist verwirrend, widersprüchlich und unvollständig. Bei Widerständen in der Zuleitung (Ausgangspoti) kommt es zum Frequenzganganstieg.
