DESCRIPTION
P3181 is an ultra-low distortion microprofile
transformer for applications where high performance
and safety isolation to international standards are
required in an extremely small case size.
Designed specifically as a surface mount device, the
P3181 features a 7mm seated height and is offered
in the same package as the now familiar P2781 and
P3081. The part is compliant with RoHS Directive
2002/95/EC, and suitable for lead-free and
conventional placement and reflow.
Despite the subminiature size, the performance is
superior to that of much larger components. The
P3181 offers reinforced insulation, is ideal for data
communications at very high data rates, and can be
matched to both 600Ω and complex impedance
telephone lines.
P3181 incorporates patented innovative features
which enable data rates of 56kbps to be
achieved.
P3181 is certified to IEC 60950 and UL 60950.
P3181 is a UL Recognized Component, and is
supported by an IEC CB Test Certificate.
