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.

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. 10mV 200Hz 10mV 200Hz Sum of windings 124 14.5 1.4 4 152 18 Ω mH H kΩ Equivalent Circuit Fig. 1 ½ L ½R ½R ½L IDEAL 1:1 Patented ETALDOC 782/4 Page 2 of 4 June 2005 P5122 MATCHING RECOMMENDATIONS 600Ω MATCH Recommended Circ uit F2 ig. 600 + 50% 6.8μF _ 20% * 270 LINE 27nF + 5% _ 33nF + 5% _ 560 + 2% _ LINE * If return loss > 16dB, 300Hz - 4kHz is ac ceptable, bloc king capacitor may be relaxed to 4.7μF + 50% _ 20% EUROPEAN CTR21 COMPLEX MATCH Recommended Circ uit F3 ig.

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.
