P3190TR

The P3190TR is designed as a high impedance microprofile transformer for applications where safety isolation to international standards is required in an extremely small case size. Designed specifically as a surface mount device, P3190 features a 7mm seated height. The P3190TR is compliant with RoHS Directive 2002/95/EC, and suitable for lead-free and conventional placement and reflow. It is designed for "listening" applications when placed across a line, presenting a high impedance exceeding 10k across the voiceband to minimize circuit loading. For applications requiring higher impedance, P2769 offers >30k in a compatible package. To meet requirements for 40k across the voiceband, P3190TR can be used in an application circuit described herein. P3190 is certified to IEC 60950 and UL 60950. P3190 is a UL recognized component and is supported by an IEC CB test certificate.

P3190TR has seven 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. Those are all the main features.

Some absolute maximum ratings of P3190TR 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 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 P3190TR are concluded as follow. (1)Its voltage isolation would be min 3.88kVrms and min 5.5kV. (2)Its input impedance would be min 10kohms at 300Hz to 3.4kHz 1Vrms. (3)Its functional operating range would be from -25°C to +85°C. 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.
