P3901

PRODUCT DATA SHEET ADSL Transformer Features ∗ ∗ ∗ ∗ ∗ ∗ Lead-free (Pb-free) Low Distortion IEC 950 and UL 60950 Certified UL Recognized Component Supplementary Insulation Surface Mount P3901 Applications ∗ Alcatel DynaMiTe CPE ∗ ADSL over ISDN DESCRIPTION P3901 is designed for Customer Premises ADSL over ISDN applications using Alcatel MTK-20140 chipset. P3901 is certified to standards IEC 950 and UL 60950 for supplementary insulation, 250V working voltage. P3901 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 P3901 exhibits excellent frequency response and balance; in combination with its good harmonic distortion performance, P3901 is ideally suited to low cost yet demanding ADSL applications.
