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 designed for “listening” applications when placed across a line, presenting a very high impedance (>50kΩ) to minimize circuit loading. 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.
