P3355

The P3355 is designed as one kind of low distortion line matching transformers which is intended for V.90 and V.92 (56kbps) modems and other high-speed applications where ultra-low distortion at moderate power levels and very low voiceband frequencies is required at a most competitive price. P3355 is offered as a direct replacement for ATS-255 in existing circuits without changes to matching components, but re-engineered for significantly improved thermal stability.

P3355 has eleven features. (1)Lead-free (Pb-free). (2)RoHS compliant. (3)Low distortion. (4)12.6mm (0.5") seated height. (5)Industry standard pinout. (6)IEC 60950 and UL 60950 certified. (7)UL recognized component. (8)Environmentally tested to IEC 68. (9)CERT reliability tested. (10)Excellent frequency response. (11)High thermal stability. (12)Directly replaces ATS-255. Those are all the main features.

Some absolute maximum ratings of P3355 have been concluded into several points as follow. (1)Its short term isolation voltage 1s would be 2.12kVrms and 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 P3355 are concluded as follow. (1)Its insertion loss would be typ 2.4dB. (2)Its frequency response would be typ 10Hz at LF -3dB cutoff and would be typ 30kHz at HF -3dB cutoff. (3)Its return loss would be min 26dB. (4)Its third harmonic distortion would be max -76dBm. (5)Its voltage isolation would be min 2.12kVrms and min 3.0kV. (6)Its DC resistance would be min 126ohms and max 154ohms for primary and would be min 173ohms and max 211ohms for secondary. (7)Its leakage inductance would be min 3.6mH and max 6mH. (8)Its shunt inductance would be min 10H and typ 23H. (9)Its shunt loss would be min 20kohms and typ 24kohms. And so on. At present we have not got so much information about this IC and we would try hard to get more information about it.
