The 786 series is a comprehensive range of
78613/2C 1CT:1 500 10 1.07 20 0.36
general purpose pulse transformers. Common
78613/8C 1CT:1 1000 15 1.13 35 0.48 1000 3
applications include line coupling, matching or
78613/1C 1CT:1 2000 20 1.53 47 0.63
isolating. The devices can also be used in small
78613/16C 1CT:1 4000 28 1.98 64 0.88
isolated power supplies and also as common-
78613/9C 1CT:1 10000 56 3.83 72 1.33
mode chokes in filtering applications.

recommended for new designs. For existing designs,
78615/16C 1CT:1CT 4000 28 37.7 20 0.87
however, Murata Power Solutions will continue to
78615/9C 1CT:1CT 10000 56 44.5 19 1.33
manufacture and fully support these parts.
