DESCRIPTION
P2824 is specifically designed to provide signal
coupling with safety isolation for FSK modems
operating at 132.45kHz such as the SGS Thomson
ST7537.
Typically, the device is driven from a low-impedance
source and connected to the mains network using a
capacitor whose value is chosen to resonate with
the transformer leakage inductance.

P2824 is certified to IEC 60950 and UL 60950 for
reinforced insulation, is a UL Recognized
Component and is supported by an IEC CB Test
Certificate. The part is completely lead-free,
compliant with RoHS Directive 2002/95/EC, and
suitable
for
lead-free
and conventional
processing.
Furthermore, the device is designed for low
distortion and meets the requirements of
EN 50065-1 for conducted emissions.
