DESCRIPTION
P5122 is intended for low-cost, low-speed data and
voice applications. It is a direct substitute for industry
standard P3189, being mechanically compatible and
having identical signal/distortion and matching
characteristics, and is suitable for supplementary
insulation, 250V working.
P5122 uses patented design and construction
methods to achieve excellent signal performance
and safety isolation to international standards.
P5122 is certified to IEC 60950 and UL 60950.
P5122 ia a UL Recognized Component and is
supported by an IEC CB certificate. 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 20dB.
2. Components are 100% tested at 3.25kV DC.
3. Caution: do not pass DC through windings.
Telephone line current, etc. must be diverted
using choke or semiconductor line hold
circuit.

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.

Figure 3 gives flat RX and TX responses against the
CTR21 complex reference impedance (typically
around ±0.5dB 300Hz - 3.4kHz). Return loss is
typically better than 20dB. The circuit values in
parentheses give optimum flatness at a small
sacrificeinreturnloss.

For circuits with existing board drillings, figure 4
gives good return loss (>20dB) and RX flatness
against the CTR21 complex reference impedance,
but TX flatness is degraded by the use of this
topology.
