DESCRIPTION
P5097 is intended for low cost V.90 and V.92
(56kbps)
modems
and
other
high-speed
applications where low distortion at moderate
power levels and very low voiceband frequencies is
required.
P5097 is offered as a direct replacement for 82097
in existing circuits without changes to matching
components.
P5097 exhibits stable core characteristics over its
operating temperature range to maximize data
throughput under varying environmental conditions
without the need for modem retraining.
P5097 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.
P5097 is certified to IEC 60950 and UL 60950.
P5097 is a UL Recognized Component and is
supported by an IEC CB certificate.

Notes:
1. Third harmonic typically exceeds other
harmonics by 10dB.
2. Components are 100% tested at 3.25kVDC.
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 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.
