DESCRIPTION

The family of transformers P2820, P2821, P2822

and P2823 is specifically designed to provide signal

coupling

with

safety

for

Powerline

Carrier

applications over four bands from 40kHz to

148.5kHz.

Typically, the devices are driven from low-

impedance sources and are connected to the mains

network using capacitors whose values are chosen

to

resonate

with

the

transformer

leakage

inductance.

They are particularly suitable for use with tri-state

power amplifiers, e.g. Texas Instruments TLE2301.

The devices are completely lead-free, compliant

with RoHS Directive 2002/95/EC, and suitable for

lead-free and conventional processing.

The devices are certified to IEC 60950 and

UL 60950 for reinforced insulation. They are UL

Recognized Components and are supported by

an IEC CB Test Certificate.

Furthermore, the

devices are designed for low distortion and meet

the requirements of EN 50065-1 for conducted

emissions.
