P5097 is offered as a direct replacement for 82097 in existing circuits without changes to matching components. P5097 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. P5097 is certified to IEC 60950 and UL 60950. P5097 is a UL Recognized Component and is supported by an IEC CB certificate. P5097 exhibits stable core characteristics over its operating temperature range to maximize data throughput under varying environmental conditions without the need for modem retraining.

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. 5. Return loss and transhybrid loss can be improved to 30dB in improved matching circuit. The values shown relate to the simplest configuration, Fig. 2.
