P3900

The P3900 is designed as a low distortion transformer for customer premises ADSL over POTS applications using the alcatel MTK-20140 and MTK-20150 chipsets. P3900 is certified to safety standards IEC 950 and UL 60950 for supplementary insulation, 250V working voltage. P3900 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 it exhibits excellent frequency response and balance; in combination with its good harmonic distortion performance, P3900 is ideally suited to low cost yet demanding ADSL applications.

P3900 has seven features. (1)Lead-free (Pb-free). (2)Low distortion. (3)IEC 950 and UL 60950 certified. (4)Supplementary insulation, (5)UL recognized component. (6)Surface mount. (7)Industry standard footprint. Those are all the main features.

Some absolute maximum ratings of P3900 have been concluded into several points as follow. (1)Its short term isolation voltage 1s would be 2.12kVrms, 3.0kVdc. (2)Its storage temperature range would be from -40°C to +85°C. (3)Its reflow temperature 10 seconds 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 P3900 are concluded as follow. (1)Its inductance would be min 440uH and typ 470uH and max 500uH. (2)Its leakage inductance would be max 8uH. (3)Its interwinding capacitance would be max 30pF. (4)Its DC resistance would be typ 0.44ohms. (5)Its turns ratio would be min 0.99 and typ 1.00 and max 1.01. (6)Its frequency response would be max +/-1.0dB from 30kHz to 3MHz. (7)Its longitudinal balance would be min 50dB. (8)Its total harmonic distortion would be max -80dB. 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 P3900.
