ETALDOC 332/14
∗ Surface Mount
∗ Lead-free (Pb- free)
∗ RoHS compliant
∗ 7mm seated height
∗ Vacuum encapsulated
∗ IEC 60950 and UL 60950 certified
∗ UL Recognized Component
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.

Applications
∗ Telecommunications
∗ Pick-off applications
∗ Calling Line Identification
∗ Instrumentation
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.
