DESCRIPTION
P5059 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.
P5059 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.
P5059 is a vacuum encapsulated version of P5056
with the benefits of greater mechanical robustness
and breakdown strength.
P5059 is certified to IEC 60950, and UL 60950,
supplementary insulation for a primary circuit,
250V working. P5059 is a UL Recognized
Component and is supported by an IEC CB Test
Certificate.
P5059 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.

Notes:
Equivalent Circuit
Fig . 1
1. Third harmonic typically exceeds other
harmonics by 10dB.
2. Components are 100% tested at 6.5kVDC.
3. Caution: do not pass DC through windings.
Telephone line current must be diverted using
semiconductor line hold circuit or choke.
4. At signal levels greater than –20dBm, Lp will
increase and Rp will decrease slightly but the
effect is usually favourable to the return loss
characteristic.

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.
