P3303

The P3303 is designed as one kind of low insertion loss line matching transformers which is intended for voice and low speed data applications where good distortion at moderate power levels is required with low insertion loss. P3303 uses patented design and construction methods to achieve excellent signal performance and safety isolation to international standards, making it the component of choice for low loss voice and data applications throughout the world. P3303 is certified to IEC 60950 and UL 60950. P3303 is a UL recognized component, and is supported by an IEC CB test certificate. The part is completely lead-free, compliant with RoHS directive 2002/95/EC, and suitable for lead-free and conventional processing.

P3303 has thirteen features. (1)Lead-free (Pb-free). (2)RoHS compliant. (3)Low insertion loss, <1dB. (4)12.6mm (0.5") seated height. (5)Industry standard pinout. (6)IEC 60950 and UL 60950 certified. (7)UL recognized component. (8)Environmentally tested to IEC 68. (9)CERT reliability tested. (10)Excellent frequency response. (11)Simple matching. (12)High thermal stability. Those are all the main features.

Some absolute maximum ratings of P3303 have been concluded into several points as follow. (1)Its short term isolation voltage 1s would be 2.12kVrms and 3.0kVdc. (2)Its DC current would be 100uA. (3)Its storage temperature range would be from -40°C to +85°C. (4)Its lead 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 P3303 are concluded as follow. (1)Its insertion loss would be typ 0.9dB at f=2kHz. (2)Its frequency response would be typ 30Hz at LF -3dB cutoff and would be typ 90kHz at HF -3dB cutoff. (3)Its return loss would be typ 20dB. (4)Its transhybrid loss would be typ 30dB at 200Hz to 4kHz. (5)Its third harmonic distortion would be typ -70dBm at 300Hz 0dBm in line and would be typ -95dBm at 600Hz -10dBm in line. 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.
