Product Details
Introduction
This shape is developed to get higher DCB characteristics when E types of ferrite cores are proper with higher current.
Features
Because plastic bobbins are used with E shape, higher productivity are available. Also good temperature stability and large energy storage capacity are available.
Applications
Multiple circuit choke coil and output chokes for SMPS. Also used for flyback transformed.
