P2769TR

The P2769TR is designed as a high impedance microprofile transformer for applications where high performance and safety isolation to international standards are required in an extremely small case size. P2769TR is designed for "listening" applications when placed across a line, presenting a very high impedance to minimize circuit loading. The part is compliant with RoHS directive 2002/95/EC, and suitable for lead-free and conventional placement and reflow.

P2769TR 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 P2769TR have been concluded into several points as follow. (1)Its storage temperature range would be from -40°C to 125°C. (2)Its soldering temperature profile peak would be 260°C for 10 seconds. (3)Its DC current would be 100uA. (4)Its short term isolation voltage 2s would be 4.6kVrms and 6.5kVdc. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device. Recommended peak body temperature 245°C in accordance with IPC/JEDEC J-STD-020.

Also some electrical characteristics of P2769TR are concluded as follow. (1)Its voltage would be min 3.88kVrms at 50Hz. (2)Its isolation would be min 5.5kV at DC. (3)Its input impedance would be min 30kohms at 200Hz to 4kHz, 1Vrms. (4)Its functional operating temperature range would be from -25°C to 85°C. (5)Its humidity would be max 95%R.H. It should be noted that components are 100% tested at 6.5 kVDC. Do not pass DC through windings. Telephone line current, etc. must be diverted using choke or semiconductor line hold circuit. At present we have not got so much information about this IC and we would try hard to get more information about it. If you have any question or suggestion or want to know more information of P2769TR please contact us for details. Thank you!
