P2883

The P2883 is designed as a microprofile transformer for ADSL applications requiring safety isolation to international standards. The ADSL requirements for good balance and frequency response, with low levels of distortion are achieved in a miniature package with a high level of safety insulation. The part is compliant with RoHS directive 2002/95/EC, and suitable for lead-free and conventional processing.

It has nine features. (1)Ultra-low profile, 7mm. (2)IEC 950 certified. (3)Supplementary insulation. (4)Lead-free (Pb-free). (5)RoHS compliant. (6)Excellent frequency characteristics. (7)Low distortion. (8)Vacuum encapsulated. (9)Use as 1:1 or 2:1 ratio. Those are all the main features.

Some absolute maximum ratings have been concluded into several points as follow. (1)Its short term isolation voltage 1s would be 2.12kVrms and 3.0kVdc. (2)Its storage temperature range would be from -40°C to 125°C. (3)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 are concluded as follow. (1)Its turns ratio would be min 0.98 and typ 1.00 and max 1.02. (2)Its primary inductance would be min 25mH and typ 40mH. (3)Its DC resistance would be typ 1.8ohms at 3-5 and 4-6 and would be typ 1.2ohms at 1-2. (4)Its interwinding capacitance would be typ 30pF. (5)Its leakage inductance would be typ 5uH and max 12uH. (6)Its insertion loss would be typ 0.25dB. (7)Its frequency response would be typ +/-0.1dB. (8)Its phase response would be typ +/-5 degrees. (9)Its longitudinal balance would be min 40dB. (10)Its return loss would be min 20dB at 30kHz to 500kHz and would be min 14dB and typ 18dB and would be min 10dB and typ 14dB at 1.1MHz to 2MHz. (11)Its total harmonic would be max -80dBc at 4Vrms. And so on. If you have any question or suggestion or want to know more information please contact us for details. Thank you!
