1690 amorphous core

222.166.160.50

the 1690 spec sheet said it is cobalt amorphous core. Is 1676 and 1674 also 'cobalt' amorphous core ? or different types of amorphous core.

All of the "small" mumetal shielded PC mount transformers that are labeled amorphous core use amorphous cobalt core material.

The LL1674, LL1676 and LL1690 are the same except for the winding ratio of the coils.
