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 600

Ω 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.
