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.

Every part on this page is wound to order, so a secondary voltage, a cover style, or a footprint outside the standard table is a quote, not a refusal.
