DESCRIPTION
P2152 is a high impedance transformer for
applications where high performance and safety
isolation are required in a compact case size.
P2152 has a turns ratio of 1.732:1 giving an
impedance transformation of 3:1.
P2152 is certified to IEC 60950 and UL 60950.
P2152 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.
P2152 is designed for “listening” applications when
placed across a line, presenting a very high
impedance (>50kΩ) to minimize circuit loading.
