DESCRIPTION
P3190 is a high impedance microprofile transformer
for
applications
where
safety
isolation
to
international standards is required in an extremely
small case size.
Designed specifically as a surface mount device,
P3190 features a 7mm seated height. The part is
compliant with RoHS Directive 2002/95/EC, and
suitable for lead-free and conventional placement
and reflow.
P3190 is designed for "listening" applications
when placed across a line, presenting a high
impedance exceeding 10k
Ω
across the voiceband
to minimize circuit loading.
For applications requiring higher impedance,
P2769 offers >30k
Ω
in a compatible package.
To meet requirements for
≥
40k
Ω
across the
voiceband, P3190 can be used in an application
circuit described herein.
P3190 is certified to IEC 60950 and UL 60950.
P3190 is a UL Recognized Component and is
supported by an IEC CB Test Certificate.
