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. ETALDOC 575/9 Page 1 of 4 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. February 2006 P3176 SPECIFICATIONS Electrical At T = 25ºC and as circuit Fig. 2 unless otherwise stated.

Third harmonic typically exceeds other harmonics by 10dB. 2. Components are 100% tested at 6.5kV DC. 3. Caution: do not pass DC through windings. 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.
