The largest one is made from N87 ferrite, while most of the rest also come in N88 or N97.
One, measuring 80 x 40 x 38mm, comes in N97, or also N95.
When even more magnetic mass is needed, the company has created plastic frames that will hold multiple E cores in stacks.
| E-core size (mm) | AL value (nH) | Core material |
|---|---|---|
| 120 x 71 x 40 | 12,500 – 15,000 | N87, N88, N97 |
| 130 x 64 x 40 | 11,000 – 13,100 | N87, N88, N97 |
| 140 x 68 x 40 | 10,700 – 12,700 | N87, N88, N97 |
| 160 x 80 x 40 | 10,700 | N87 |
| 80 x 38 x 40 | 12,200 or 9,900 | N95 or N97 |
For simulation, TDK’s ‘Ferrite magnetic design tool’ is available.
Other potential applications are railway, wind and solar inverters, and welding.
