MATCHING TRANSFORMER
Features
ETALDOC 240/9
P2781 is a 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
P2781 features a 7mm seated height and is vacuum
encapsulated and tested to 6500VDC.
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, whilst capable of being matched to
both 600

Applications
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.
