DESCRIPTION
P5100 is intended for low-cost, medium-speed data
and voice applications. It is a direct substitute for
industry standard P1200, being mechanically
compatible and having identical signal/distortion
and matching characteristics, and suitable for
supplementary insulation, 250V working.
P5100 uses patented design and construction
methods to achieve excellent signal performance
and safety isolation to international standards.
P5100 is certified to IEC 60950 and UL 60950.
P5100 is 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.

Equivalent Circuit
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
sacrifice in return loss.
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.
