P3302 is offered as a more compact internationally safety approved substitute for XM-1025, 2802-B and 671-8079 in existing circuits without changes to matching components. P3302 uses patented design and construction methods to achieve excellent signal performance and safety isolation to international standards. P3302 is certified to IEC 60950 and UL 60950. P3355 is a UL Recognized Component and is supported by an IEC CB Test Certificate. The part is completely lead-free, compliant with RoHS Directive 2002/95/EC, and suitable for lead-free and conventional processing. P3302 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.

Third harmonic typically exceeds other harmonics by 10dB. 2. Components are 100% tested at 3.25kVDC. 3. Caution: do not pass DC through windings. Telephone line current must be diverted using semiconductor line hold circuit or choke. 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. 200Hz 1V 200Hz 1V Primary Secondary 126 130 3.6 8 16 18 19 154 160 5.4 Ω Ω mH H kΩ Equivalent Circuit Fig. 1 ½L R R ½L IDEAL 1:1 Patented ETALDOC 770/3 Page 2 of 5 April 2005 P3302 600Ω Referenc e Circuit Fig. 2 600 22μF 300* T XA1 LINE 10nF T XA2 * Increase to 430 to improve RX loss.
