DESCRIPTION
P3034 is intended for V.34plus applications where
low distortion at moderate power levels is required
at a competitive price.
P3034 is a drop-in replacement for industry
standard P1200 for circuits to be upgraded to
V.34plus (33,600 bits/second). P3034 is also
mechanically and electrically compatible with P2001.

P3034 meets international safety standards,
being vacuum encapsulated and 100% tested to
withstand 6.5kV DC. The part is completely
lead-free, compliant with RoHS Directve
2002/95/EC, and suitable for lead-free and
conventional processing.
P3034 is certified to IEC 60950 and UL 60950.
P3034 is a UL Recognized Component and is
supported an IEC CB Test Certificate.

Notes
Equivalent Circuit
1. Third harmonic typically exceeds other
harmonics by 20dB.
2. Components are 100% tested at 6.5kV 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.
