DESCRIPTION
P5033 is intended for low cost V.90 and V.92
(56kbps)
modems
and
other
high-speed
applications. It is a direct substitute for P3356,
being mechanically compatible and having identical
signal/distortion and matching characteristics, and
suitable for supplementary insulation, 250V
working.
P5033 uses patented design and construction
methods to achieve excellent signal performance
and safety isolation to international standards. The
part is completely lead-free, compliant with RoHS
Directive 2002/95/EC, and suitable for lead-free
and conventional processing.
P5033 also exhibits stable characteristics over its
full operating temperature range to maximize
data throughput under varying environmental
conditions without the need for modem
retraining.
P5033 is certified to IEC 60950 and UL 60950.
P5033 is a UL Recognized Component and is
supported by an IEC CB certificate.
P5033 has exceptionally flat frequency response
from 30Hz to 10kHz, a 3dB bandwidth of 60kHz
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.

Notes:
Equivalent Circuit
1. Third harmonic typically exceeds other
Fig. 1
harmonics by 10dB.
2. Components are 100% tested at 3.25kVDC.
3. Caution: do not pass DC through windings.
IDEAL
Telephone line current must be diverted using
½ L
½ L
1:1
semiconductor line hold circuit or choke.
4. At signal levels greater than 100mV, Lp will
increase and Rp will decrease slightly but the
effect is usually favourable to the return loss
characteristic.
5. Return loss and transhybrid loss can be
improved to 30dB in improved matching circuit.
The values shown relate to the simplest
configuration, Fig. 2.
6. At signal frequencies, the primary and secondary resistance appear in series with the load and therefore
present a sum of resistances in the range 165-207Ω in common with P3356.

MATCHING RECOMMENDATIONS
The following recommendations start with the simplest implementations and progress to enhanced
performance utilizing additional components.
Good performance is achieved even with the simplest
configurations. The implementations assume a low impedance balanced TX drive and a relatively high
impedance RX input, as is commonly available, though use with other TX/RX arrangements is
straightforward. Note that there are no changes to components on the line side, or in the hybrid, whether
600Ω or complex reference impedance selected, thus assisting country configuration. For complex
impedance, the matching circuits derived are suitable for reference impedances of the type 270 + 750//150nF
e.g. European CTR21 and 220 + 820//120nF (or 115nF) e.g. Australia, South Africa, etc., and yield similar
performance characteristics. For other impedances, please contact Profec Technologies.
