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.
