Description
GENERAL INFORMATION ::
E cores are less expensive as compared to other cores, and may have the advantages of simple bobbin winding plus easy assembly. Gang winding is possible for bobbins used with these cores. E cores do not, however, offer self-shielding. E cores are popular shapes due to their lower cost, ease of assembly and winding, and the ready availability of a variety of hardware.
TYPICAL CHARATERSTICS ::
- Magnetics Shielding : External magnetic field generated due to exposed winding
- Cost of Core : Low
- Cost of Winding & Assembly : Low
- Heat Dissipation : Very Good
- Uniform Cross Section : Yes
APPLICATIONS ::
- Switch Mode Power Supplies (SMPS)
- Audio Transformers
- Impedance Matching
- Sensing Transformers
- Signal Distribution Transformers for communications.
- Pulse Transformers
- Isolation Transformers
