DESCRIPTION
P2782 is a microprofile transformer with one
centre-tapped winding 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
P2782 features a 7mm seated height and is vacuum
encapsulated and tested to 6500VDC. 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
the equal of that of much larger components. The
P2782 offers reinforced insulation, is ideal for voice
telecommunications and for data communications to
V.22bis (2,400 bits/second), and can be matched to
both 600Ω and complex impedance telephone lines.
At moderate transmit power levels (e.g. -10dBm)
performance to V.32bis may be achieved.
In instrumentation applications, the P2782 offers a
wideband frequency response from 50Hz to
40kHz.
P2782 is certified to IEC 60950 and UL 60950.
P2782 is a UL Recognized Component, and is
supported an IEC CB Test Certificate.
