For the 2SC5703 there is this 167 KB PDF, catalogued as a schematic but almost certainly a part datasheet, since 2SC denotes an NPN bipolar transistor in the JIS system.

The 2SC2347 is the subject of this 292 KB PDF, filed as a schematic but most likely a datasheet for the NPN transistor.

Component documentation for the 2SA1296, delivered as a 219 KB PDF. The filename gives nothing beyond the part number; 2SA indicates a PNP bipolar transistor in the JIS…

PDF sheet, 218 KB, for the 2SA1049 transistor, indexed as a schematic. The 2SA prefix identifies a PNP bipolar device under Japanese JIS registration.

Schematic diagram in PDF for Compal notebook board LA-C701P. The name gives no revision or laptop model, so compare the board number and revision printed on your PCB…

Compact 70.2 KB datasheet in PDF, named only by the literature number SDNS029C, with the C suffix probably denoting a later revision.

Datasheet of 216 KB in PDF format, labelled SDNS015C, which is a literature code with a revision letter rather than a component name.

SN74161N datasheet, a 25.6 KB PDF for the synchronous presettable 4-bit binary counter with asynchronous clear, supplied in plastic DIP (N suffix).

Datasheet in PDF form for a part marked C4581. The name gives only this code, which may be an abbreviated transistor marking, so check the document header to confirm the…

Samsung firmware dump named np150, a 2 MB raw image apparently for the NP150 series netbook. No board number or revision appears in the name.

Unlabelled-type archive, 2.09 MB, named 3CESLRH131, which may denote revision 13.1 of the 3CESL RH series, although that reading is not certain.

Xiaomi Mi 3 logic block diagram combined with board position drawings, according to the Chinese name, in a 2.57 MB PDF.
