P5273

The P5273 is designed as one kind of low distortion line matching transformers with typical applications of V.90 and V.92 modems and V.34 modems.

P5273 has eleven features. (1)Lead-free (Pb-free). (2)RoHS compliant. (3)Low distortion. (4)10.4mm (0.41'') seated height. (5)Industry standard pinout. (6)IEC 60950 and UL 60950 certified. (7)Supplementary insulation for a primary circuit. (8)Extended frequency response. (9)Flat TX and RX responses. (10)High thermal stability. (11)Directly replaces 2811B, ATS-273 and LCT0035A. Those are all the main features.

Some absolute maximum ratings of P5273 have been concluded into several points as follow. (1)Its short term isolation voltage 1s would be 2.12kVrms, 3.0kVdc. (2)Its DC current would be 100uA. (3)Its storage temperature range would be from -40°C to +85°C. (4)Its lead temperature 10s would be 260°C. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some electrical characteristics of P5273 are concluded as follow. (1)Its insertion loss would be max 2.0dB with conditions of f=2kHz and RL=600ohms. (2)Its frequency response would be typ 10Hz at LF-3dB cutoff and would be typ 30kHz at HF-3dB cutoff and would be max +/-0.1dB at 100Hz to 4KHz. (3)Its return loss would be min 20dB at 200Hz to 4KHz and would be min 25dB at 200Hz to 3.5kHz. (4)Its third harmonic distortion would be max -76dBm at 150Hz-3dBm in line. (5)Its balance would be min 80dB at DC-5kHz method TG 25.(6)Its voltage isolation would be min 2.12kVrms at 50Hz and would be min 3.0kV at DC. (7)Its operating range would be from 0°C to +70°C for functional and would be from -40°C to +85°C for storage. (8)Its DC resistance would be min 120ohms and max 149ohms for primary resistance Rdcp.
