Designed specifically as a surface mount device, P3190 features a 7mm seated height. The part is compliant with RoHS Directive 2002/95/EC, and suitable for lead-free and conventional placement and reflow. P3190 is designed for "listening" applications when placed across a line, presenting a high impedance exceeding 10kΩ across the voiceband to minimize circuit loading. For applications requiring higher impedance, P2769 offers >30kΩ in a compatible package. To meet requirements for ≥40kΩ across the voiceband, P3190 can be used in an application circuit described herein. P3190 is certified to IEC 60950 and UL 60950. P3190 is a UL Recognized Component and is supported by an IEC CB Test Certificate. ETALDOC 725/12 Page 1 of 5 October 2007 P3190 SPECIFICATIONS Electrical At T = 25°C unless otherwise stated.

The DC blocking capacitor should be maintained within the range 0.22µF to 0.33µF to obtain a flat frequency response and input impedance to specification. 47k Zin 40kΩ APPLICATION CIRCUITS For applications requiring impedance greater than 40kΩ for parallel-connected Terminal Equipment (e.g. ETSI TS 103 021, ≥40kΩ, 200Hz – 4.3kHz) the following circuits may be helpful. At the expense of a small loss, the circuit in Fig. 3 provides an impedance exceeding 40kΩ from DC upwards. 39k 47n F3 ig 270k P3190 Zin > 40kΩ F4 ig 39k 68n 6.8n 39k P3190 RLoad Vout Due to the finite primary inductance of the P3190, the circuit of Fig. 3 suffers from low frequency rolloff below 500Hz. At the expense of around 6dBV loss, the circuit of Fig. 4 provides a relatively flat response from 300Hz to 4kHz. The load resistance, RLoad, across which the output voltage appears, should be a minimum of 470kΩ, and can be increased without limit.
