DESCRIPTION
P3357 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
competitive price.
P3357 is a vacuum encapsulated version of P3356
with the benefits of greater mechanical robustness
and breakdown strength. The part is completely
lead-free, compliant with RoHS Directive
2002/95/EC, and suitable for lead-free and
conventional processing.
P3357 uses patented design and construction
methods to achieve excellent signal performance
and safety isolation to international standards.
P3357 is certified to IEC 60950 and UL 60950.
P3357 is a UL Recognized Component and is
supported by an IEC CB Test Certificate.
P3357 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.
