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. P3800 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. P3800 is certified to IEC 60950 and UL 60950. P3800 is a UL Recognized Component and is supported by an IEC CB Test Certificate. P3800 is a rugged lightweight design that has been subjected to relevant environmental testing according to IEC 68 and Combined Environmental Reliability Testing (CERT) beyond normal operational levels and passed all tests, remaining fully functional Patented ETALDOC 710/8 Page 1 of 5 April 2005 P3800 SPECIFICATIONS Electrical At T = 25ºC and as circuit fig. 2 unless otherwise stated.

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 120 14.5 2.8 5 148 18 Ω mH H kΩ Equivalent Circuit Fig. 1 ½ L ½R ½R ½L IDEAL 1:1 Patented ETALDOC 710/8 Page 2 of 5 April 2005 P3800 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. 150nF (150nF) 100nF 2.2μF 750 56nF 750 (680) 150 (220) 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.
