DESCRIPTION
P3900 is a low distortion transformer for Customer
Premises ADSL over POTS applications using the
Alcatel MTK-20140 and MTK-20150 chipsets.
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.
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.
