PRODUCT DATA SHEET LOW DISTORTION P3801 LINE MATCHING TRANSFORMER Features Applications Lead-free (Pb-free) V.90 and V.92 modems RoHS compliant V.34 modems Low distortion Environmentally tested to IEC 68 CERT reliability tested 12.6mm (0.5 ) seated height Industry Standard Pinout Extended Frequency Response IEC 60950 and UL 1950 Certified UL Recognized Component High thermal stability DESCRIPTION P3801 is intended for high-speed applications where P3801 uses patented design and construction low distortion at moderate power levels and very low methods to achieve excellent signal performance voiceband frequencies is required at the most and safety isolation to international standards. The competitive price. At moderate power levels part is completely lead-free, compliant with RoHS (e.g. -10dBm) performance to V.90/V.92 may be Directive 2002/95/EC, and suitable for lead-free and achieved. conventional processing. P3801 has extended flat frequency response from P3801 is certified to IEC 60950 and UL 60950. 30Hz to 4kHz with very low levels of signal distortion P3801 is a UL Recognized Component and is at signal frequencies as low as 150Hz. supported by an IEC CB Test Certificate. P3801 is electrically and mechanically compatible P3801 is a rugged lightweight design that has with P3034 and P2001 for supplementary been subjected to relevant environmental testing insulation 250V working applications, and directly according to IEC 68 and Combined replaces 9002VF, 671-8236M, MTLM 2001, Environmental Reliability Testing (CERT) beyond EMIT-2001, and ATS-091/B without changes to normal operational levels and passed all tests, matching components, but with the added benefit remaining fully functional. of considerably improved thermal stability. P3801 also offers a drop-in performance upgrade path for P3800 and P1200.

Third harmonic typically exceeds other Fig. 1 harmonics by 20dB. 2. Components are 100% tested at 3.25kV DC. 3. Caution: do not pass DC through windings. IDEAL L R R L Telephone line current, etc. must be diverted 1:1 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.
