DESCRIPTION
P3081 is 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 P3081 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 P3081 offers reinforced insulation, is ideal for data communications at high data rates, and can be matched to both 600 Ω and complex impedance telephone lines. At moderate transmit power levels (e.g. -10dBm) performance to 33,600 bits/second may be achieved. P3081 is certified to IEC 60950 and UL 60950. P3081 is a UL Recognized Component, and is supported by an IEC CB Test Certificate.

Third harmonic typically exceeds other harmonics by 20dB. 2. Components 100% tested at 6.5 kVDC. 3. Caution: do not pass DC through windings. Telephone line current, etc. must be diverted using choke or semiconductor line hold circuit. 4. At signal levels greater than 100mV, Lp will increase and Rp will decrease slightly but the effect is usually favourab le to the return loss characteristic. 5. Excludes shipping materials. Components are dry-packed and sealed as shipped Handle in accordance with IPC/JEDEC J-STD-033 procedure for components classified as IPC/JEDEC J-STD-020 Moisture Sensitivity Level 5a.

ETALDOC 459/11 Page 3 of 4 October 2007 PERFORMANCE In practice, the 600Ω load resistor will connect to a low output impedance TX driver. The 150nF capacitor should appear in parallel with the 680Ω load resistor (rather than in parallel with transformer winding) to obtain optimum TX flatness to line.
