For the 2SC5439 transistor, this 192 KB PDF is most likely a manufacturer datasheet, given that 2SC is the JIS designation for NPN bipolar parts.

Component documentation for the 2SC3669 in PDF format, 192 KB in size. The 2SC prefix in Japanese JIS numbering indicates an NPN bipolar transistor, and the bare…

Datasheet-type PDF, 195 KB, for the transistor 2SA1971, whose 2SA prefix marks a PNP bipolar device under the Japanese JIS scheme.

Datasheet PDF of 190 KB for the 2SA1761, filed under the schematic type. In the JIS scheme the 2SA prefix denotes a PNP bipolar transistor, and the name gives nothing…

This 193 KB PDF, catalogued under schematics, is named 110cnq045a, which reads as a discrete power component code rather than a board identifier.

A 199 KB PDF for the 8ETH03 part, listed as a schematic in the index. The name fits the International Rectifier and Vishay hyperfast rectifier coding, so expect a…

Small RAR archive for Compal board LA-9632P, project VIWGP, revision 1.0. At 199 KB it most likely holds a boardview rather than the full schematic, though the contents…

CADSee version 4 in a Touch edition, distributed as a 19.4 MB ZIP archive. CADSee is a Windows program for viewing motherboard layout and boardview files, and the Touch…

Archive named 3AESV-RH-11, an uninformative code that seems to identify a board and revision but states no brand, model or file type.

Labelled 2SD2526, this 192 KB PDF contains reference data for a Japanese-coded transistor rather than a device-level circuit.

2SC5154 is the only detail in this 198 KB PDF name, and that JIS designation points to an NPN bipolar transistor of the high-frequency group, so treat the file as a…

A 195 KB PDF labelled with the transistor type 2SC4210. No device, board or manufacturer is named; the 2SC prefix simply tells us, through the Japanese JEITA system…

Datasheet-type PDF of 197 KB for the 2SA2069 transistor, indexed under schematics. Following JIS naming, the 2SA prefix identifies a PNP transistor intended for…

Part-number document for 2SA2056, stored as a 191 KB PDF and listed in the schematic section.

Component sheet for the 2SA1925 in a 198 KB PDF, labeled as a schematic though the plain part-number name suggests a manufacturer datasheet.

A 19.2 KB PDF for part number 1SV294, classified here as a schematic. The 1SV family generally consists of varactor diodes, so the document should describe one discrete…

Identified only as 115cnq015a, this 193 KB PDF sits in the schematic category with no board number, revision or product mentioned.

Named 20ETF-FP, this 198 KB PDF sits in the schematic category but states no laptop brand, board number or revision.

PDF schematic for the Compal LA-A972P laptop motherboard, 1.19 MB. The file name gives only the board identifier, so brand, model and revision are not stated.
