ATB322515-0110-T000 is an audio transformer/signal transformer manufactured by TDK. It is a miniature high-performance audio transformer that is designed to be used in signal line circuits, such as for connecting two lines to isolate noise. It is especially suited for connecting digital audio circuits. It features a maximum primary current of 1.2A, and is rated with a maximum frequency response of up to 100 kHz at 10 dB points. Its isolation voltage and impedance are rated at 1500Vrms and 500O, respectively. The transformer also has a shield plate between windings to reduce leakage inductance and improve common mode noise rejection. The case size measures 22.9 x 15.7 x 10.4 mm.
