P3910

The P3910 is designed as one kind of a low distortion transformer for ADSL over POTS applications. It is certified to safety standards IEC 950 and UL 60950 for supplementary insulation, 250V working voltage. P3910 is a UL recognized component and is supported by an IEC CB test certificate. The part is completely lead-free and suitable for lead-free and conventional processing. The safety system yields very low transformer parasitics, ensuring that P3910 exhibits excellent frequency response and balance; in combination with its good harmonic distortion performance, P3910 is ideally suited to low cost yet demanding ADSL applications.

P3910 has seven features. (1)Lead-free (Pb-free). (2)Low distortion. (3)IEC 950 and UL 60950 certified. (4)UL recognized component. (5)Supplementary insulation. (6)Surface mount. (7)Industry standard footprint. Those are all the main features.

Some absolute maximum ratings of P3910 have been concluded into several points as follow. (1)Its short term isolation voltage 1s would be 2.12kVrms and would be 3.0kVdc. (2)Its storage temperature range would be from -40°C to +85°C. (3)Its reflow 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 P3910 are concluded as follow. (1)Its inductance would be min 4.5mH and typ 5.0mH and max 5.5mH. (2)Its leakage inductance would be max 15uH. (3)Its interwinding capacitance would be ma 50pF. (4)Its DC resistance would be typ 1.6ohms for 1-3, 2-4 and would be typ 0.9ohms for 7-9, 8-10. (5)Its truns ratio would be typ 2.125. (6)Its voltage isolation would be min 2.12kVrms and min 3.0kV. (7)Its functional operating temperature range would be from -40°C to +85°C. It should be noted that components are 100% tested at 3.25kV DC. 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 P3910.
