PRODUCT DATA SHEET MICROPROFILE LINE P2781 MATCHING TRANSFORMER Features Applications Surface Mount Telecommunications Lead-free (Pb-free) V.22bis and V.32bis modems RoHS compliant Line matching 7mm seated height Portable computers Vacuum encapsulated Instrumentation IEC 60950 and UL 60950 certified UL Recognized Component DESCRIPTION P2781 is a microprofile transformer for applications At moderate transmit power levels (e.g. -10dBm) where high performance and safety isolation to performance to V.32bis may be achieved. international standards are required in an extremely small case size. In instrumentation applications, the P2781 offers a wideband frequency response from 50Hz to Designed specifically as a surface mount device, the 40kHz. P2781 features a 7mm seated height and is vacuum encapsulated and tested to 6500VDC. The part is P2781 is certified to IEC 60950 and UL 60950. compliant with RoHS Directive 2002/95/EC, and P2781 is a UL Recognized Component, and is suitable for lead-free and conventional placement supported by an IEC CB Test Certificate. and reflow. Despite the subminiature size, the performance is the equal of that of much larger components. The P2781 offers reinforced insulation, is ideal for voice telecommunications and for data communications to medium speed, and can be matched to both 600 and complex impedance telephone lines.
