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 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 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 been subjected to relevant
environmental testing according to IEC 68 and
Combined Environmental Reliability Testing
(CERT) beyond normal operational levels and
passed all tests, remaining fully functional.
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.
