Ferrite Cores for Switching Power Supplies
Product compatible with RoHS directive
Halogen-free
Overview of the EPC Series
FEATURES
TDK’s original shapes
The EPC Cores have low profiles, and so are useful in situations where mounting is subject to restrictions.
APPLICATION
Tranformers and coils for Switched-mode power supplies (High Mounting Density, Low Profile)
