DESCRIPTION
The 786 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.
Operating free air temperature range 0°C to 70°C
Storage temperature range --60°C to 125°C
Lead Temperature 1.5mm from case for 10 seconds 300°C
ABSOLUTE MAXIMUM RATINGS
SELECTION GUIDE
All specifications typical at TA=25°C
1. If components are required in SMD, suffix order code with ‘M-R’ e.g. 78601/1M-R.
