P5273 is offered as a direct replacement for 2811B, ATS-273/ATS-273B and LCT0035A in existing circuits without changes to matching components. FOR NEW DESIGNS P5233 IS RECOMMENDED ETALDOC 852/4 P5273 uses patented design and construction methods to achieve excellent signal performance and safety isolation to international standards. P5273 is certified to IEC 60950 and UL 60950. P5273 is 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 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.
