DESCRIPTION
The 766 series is a comprehensive range of 
general purpose pulse transformers. Common 
applications include line coupling, matching 
or isolating. The devices can also be used in 
small isolated power supplies and also as 
common-mode chokes in filtering 
applications. Please contact the technical 
support desk to discuss your requirements.
