DESCRIPTION

P3921 is a low distortion transformer for HDSL2

and G.SHDSL applications.

P3921 is certified to safety standards IEC 950 and

UL 60950 for supplementary insulation, 250V

working voltage. P3921 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 P3921 exhibits excellent

frequency response and balance; in combination

with its good harmonic distortion performance,

P3921 is ideally suited to low cost yet demanding

applications.
