P3900 is certified to safety standards IEC 950 and UL 60950 for supplementary insulation, 250V working voltage. P3900 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. ETALDOC 741/8 Page 1 of 4 The safety system yields very low transformer parasitics, ensuring that P3900 exhibits excellent frequency response and balance; in combination with its good harmonic distortion performance, P3900 is ideally suited to low cost yet demanding ADSL applications.
