- E Core
- E-Cores are made of alloy powder which has low losses at elevated temperature and has relatively stable inductance over temperature. Sendust E-cores have a distributed air gap which makes them ideally suited for switching regulator inductors and power factor correction(PFC) inductors. 10,000Gauss saturation level of Sendust provides a higher energy storage capability than can be obtained with gapped ferrite E-cores, thus resulting in a smaller core size. Sendust E-cores are competitively priced against gapped ferrite E-cores and their distributed air gap eliminates gap loss problems associated with ferrites. Sendust E-cores have significantly lower losses and substantially better thermal properties when compared iron E-cores. A selection of standard E cores is available along with the ability to produce custom dimensions and other geometries.
- - Excellent DC-biased inductance - No magnetic flux leakage - Good temperature stability - Low core loss at high frequ - Large energy storage capacity
- - Large current choke coils - Flyback transformers - Multiple circuit choke coils - PFC reactors - Output choke for SMPS
