DESCRIPTION

P3356 is intended for V.90 and V.92 (56kbps)

modems and other high-speed applications where

ultra-low distortion at moderate power levels and

very low voiceband frequencies is required at a

most competitive price.

P3356 uses patented design and construction

methods to achieve excellent signal performance

and safety isolation to international standards,

making it the component of choice for high-speed

data applications throughout the world. P3356 is

certified to IEC 60950, UL 60950 and EN 60950.

P3356 is a UL Recognized Component, and is

supported by IEC CB and Demko Certificates. The

part is completely lead-free, compliant with RoHS

Directive 2002/95/EC, and suitable for lead-free

and conventional processing.

P3356 has exceptionally flat frequency response

from 30Hz to 10kHz, a 3dB bandwidth of over

50kHz and requires only the very simplest of

matching to achieve good return loss and

transhybrid loss across the voiceband, with very

low levels of signal distortion at signal frequencies

as low as 150Hz.

P3356 is a rugged lightweight design that

exhibits stable characteristics over its full

operating temperature range to maximize data

throughput

under

varying

environmental

conditions

without

the

need

for

modem

retraining.

P3356

has

been

subjected

to

relevant
