Project Description

EQ cores

EQ ferrite cores are derived from ER cores and PQ cores. The range is optimized for use in compact AC/DC notebook adapters and DC/DC converters. For instance, the EQ30 has the capability to handle a power range of 50W to 70W (flyback topology) in an enclosed casing of a notebook adapter or 100W to 150W in a low profile DC/DC converter.

Advantages of EQ cores:

    • Simple core shape
    • Round center pole
    • High Ae Value
    • large winding window
    • low profile
    • large surface area for heat dissipation.
