ADSL over ISDN (Annex B)
DESCRIPTION
P5342 is a low distortion transformer for ADSL
over ISDN (Annex B) applications.
P5342 is certified to IEC 60950 and UL 60950 for
supplementary insulation for a primary circuit, 250V
working voltage. P5342 is a UL Recognized
Component and is supported by an IEC CB Test
Certificate. The part is completely lead-free,
compliant with RoHS Directive 2002/95/EC, and
suitable for lead-free and conventional processing.
The safety system yields very low transformer
parasitics, ensuring that P5342 exhibits excellent
frequency response and balance; in combination
with its good harmonic distortion performance,
P5342 is ideally suited to low cost yet demanding
ADSL applications.
