This series has been withdrawn from the current catalog

The 80VA-EI78-40.5-KK datasheet is no longer part of pcb mount transformers production and these part numbers cannot be ordered. The page and the drawing stay published for anyone maintaining a design that already uses one — open a part number below to see the active parts it can be requoted against.

Send the specification and we will quote the same wind as a custom build.

Current is quoted per secondary winding, so a dual-winding part delivers the listed current on each of its two windings rather than splitting it between them. No-load voltage is the open-circuit secondary before the winding is loaded — expect it to sit above the rated figure.
