PRODUCT DATA SHEET ULTRA LOW DISTORTION LINE MATCHING TRANSFORMER Features ∗ ∗ ∗ ∗ ∗ ∗ ∗ ∗ ∗ Lead-free (Pb-free) RoHS compliant Low Distortion 12.6mm (0.5") seated height Extended Frequency Response IEC 60950 and UL 60950 certified UL Recognized Component Flat TX and RX Responses High Thermal Stability P3176 Applications ∗ V.90 and V.92 modems DESCRIPTION P3176 is intended for V.90 and V.92 (56kbps) modems and other high-speed applications where low distortion at high power levels and very low voiceband frequencies is required at a competitive price. P3176 is mechanically compatible with industry standard P1200 and P2001 and electrically and mechanically compatible with P3146. P3176 has extended flat frequency response from 30Hz to 4kHz with very low levels of signal distortion at signal frequencies as low as 150Hz. P3176 also exhibits stable characteristics over its operating temperature range to maximize data throughput under varying environmental conditions without the need for modem retraining. P3176 meets international safety standards, being vacuum encapsulated and 100% tested to withstand 6.5kV. The part is completely lead-free, compliant with RoHS Directive 2002/95/EC, and suitable for lead-free and conventional processing. P3176 is certified to IEC 60950 and UL 60950. P3176 is a UL Recognized Component and is supported an IEC CB Test Certificate.

Telephone line current, etc. must be diverted using semiconductor line hold circuit. 4. At signal levels greater than 100mV, Lp will increase and Rp will decrease slightly but the effect is usually favourable to the return loss characteristic.
