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 600

Ω and complex impedance

telephone lines.

When

used

with

600

Ω 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.
