P3191

The P3191 is designed as a low distortion microprofile transformer for applications where high performance and safety isolation to international standards are required in an extremely small case size. Designed specifically as a surface mount device, the P3191 features a 7mm seated height and is offered in the same package as the now familiar P2781. The part is compliant with RoHS directive 2002/95/EC, and suitable for lead-free and conventional placement and reflow. Despite the subminiature size, the performance is superior to that of much larger components. The P3191 offers reinforced insulation, is ideal for data communications at high data rates, and can be matched to both 600 and complex impedance telephone lines.

P3191 has eight features. (1)Surface mount. (2)Lead-free (Pb-free). (3)RoHS compliant. (4)7mm seated height. (5)Vacuum encapsulated. (6)IEC 60950 and UL 60950 certified. (7)UL recognized component. (8)Simple 600 match. Those are all the main features.

Some absolute maximum ratings of P3191 have been concluded into several points as follow. (1)Its short term isolation voltage 2s would be 4.6kVrms and 6.5kVdc. (2)Its DC current would be max 100uA. (3)Its storage temperature range would be from -40°C to +125°C. (4)Its soldering temperature profile peak would be 260°C 10 seconds. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some electrical characteristics of P3191 are concluded as follow. (1)Its insertion loss would be max 4.5dB. (2)Its frequency response would be typ 50Hz at -3dB LF cutoff and would be typ 35kHz at -3dB HF cutoff. (3)Its return loss would be min 16dB. (4)Its third harmonic distortion would be typ -93dBm. (5)Its balance would be min 80dB. (6)Its saturation would be max 10Vrms and max 65Vpeak. 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.
