DESCRIPTION
P2769 is a high impedance microprofile transformer
for applications where high performance and safety
isolation to international standards are required in an
extremely small case size.
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.

Reference Circuit
In practice, the 100kΩ load can be increased
without limit. 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.

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.
