P2769 is designed for “listening” applications when placed across a line, presenting a very high impedance to minimize circuit loading. The part is compliant with RoHS Directive 2002/95/EC, and suitable for lead-free and conventional placement and reflow. To meet requirements for ≥ 40kΩ across the voiceband, P2769 can be used in an application circuit described herein. P2769 is certified to IEC 60950 and UL 60950. P2769 is a UL Recognized Component, and is supported by an IEC CB Test Certificate.

The DC blocking capacitor should be a minimum of 0.22µF to avoid resonance within the voiceband to obtain a flat frequency response and input impedance to specification. 100k P2769 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 circuit may be helpful. At the expense of a small loss, (approximately 1.5dBV) the circuit in fig. 3 provides an impedance exceeding 40kΩ, 200Hz – 4.3kHz, and frequency response flatness within ±0.25dB over the same band. 100k F3 ig 15k 33n P2769 Zin > 40kΩ ETALDOC 332/14 Page 3 of 5 October 2007 P2769 CONSTRUCTION Dimensions F4 ig 2.54 2.54 (0.1) (0.1) Connections Fig 5 e3 9.0 max (0.36) 7.0 max (0.28) 13.0 max (0.51) 1 2 3 6 5 4 1.77 (0.07) 1.32 (0.052) 1.5 (0.06) NOT : E Dimensions shown are in millimetres (inches) Dimensions shown are in millimetres (inches).
