DESCRIPTION
P3191 is a 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
P3191 features a 7mm seated height and is offered
in the same package as the now familiar P2781.
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
P3191 offers reinforced insulation, is ideal for data
communications at high data rates, and can be
matched to both 600Ω and complex impedance
telephone lines.
When used with 600Ω lines no external
compensation components are required.
At moderate transmit power levels (e.g. -10dBm)
performance to 33,600 bits/second may be
achieved.
P3191 is certified to IEC 60950 and UL 60950.
P3191 is a UL Recognized Component, and is
supported an IEC CB Test Certificate.
