DESCRIPTION

P2781 is a microprofile transformer for applications

where high performance and safety isolation to

international standards are required in an extremely

small case size.

At moderate transmit power levels (e.g. -10dBm)

performance to V.32bis may be achieved.

In instrumentation applications, the P2781 offers a

wideband frequency response from 50Hz to

40kHz.

Designed specifically as a surface mount device, the

P2781 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.

P2781 is certified to IEC 60950 and UL 60950.

P2781 is a UL Recognized Component, and is

supported by an IEC CB Test Certificate.

Despite the subminiature size, the performance is

the equal of that of much larger components. The

P2781 offers reinforced insulation, is ideal for voice

telecommunications and for data communications to

medium speed, and can be matched to both 600Ω

and complex impedance telephone lines.
