A 102 KB PDF for the 2SC4635, a JIS-designated NPN transistor, most likely the full datasheet; a companion LS-variant file exists in the same series.

Spanish PDF titled Puntas de prueba, meaning test probes, 101 KB, with no device named.

Spanish basic electronics guide, a general introduction rather than a schematic for any specific equipment. The name gives no device or board number.

This 55 KB PDF is labelled 2SK2220 and indexed under schematics, though a part-number name usually means the datasheet of a single semiconductor.

PDF of 116 KB named after the 2SC4865, listed among schematics though the name signals a discrete part.

A 115 KB PDF for the 2SC3643. In Japanese JIS numbering the 2SC prefix denotes an NPN bipolar transistor, and the bare name suggests a manufacturer datasheet instead of…

Component data for the 2SA1382 in a 227 KB PDF, placed in the schematic category of the index.

Compact 27.9 KB PDF datasheet for the 2SA1812 transistor, indexed under schematics. In JIS nomenclature, 2SA marks a PNP bipolar transistor, so this sheet should…
