PRODUCT DATA SHEET ADSL Transformer Features ∗ ∗ ∗ ∗ ∗ Lead-free (Pb-free) Low Distortion IEC 950 and UL60950 Certified UL Recognized Component Supplementary Insulation P3936 Applications ∗ ADSL over POTS DESCRIPTION P3936 is a low distortion transformer for ADSL over POTS applications. P3936 is certified to safety standards IEC 950 and UL 60950 for supplementary insulation, 250V working voltage. P3936 is a UL Recognized Component and is supported by an IEC CB Test Certificate. The part is completely lead-free and suitable for lead-free and conventional processing. The safety system yields very low transformer parasitics, ensuring that P3936 exhibits excellent frequency response and balance; in combination with its good harmonic distortion performance, P3936 is ideally suited to low cost yet demanding ADSL applications.
