The 2SK2171 referenced in this 180 KB PDF is an N-channel field-effect transistor by JIS/EIAJ convention, which uses the 2SK prefix for that class.

Documentation for the 2SK1431, a part whose 2SK prefix places it among N-channel FETs under Japanese JIS numbering.

Component documentation for the 2SK1033, a 34.4 KB PDF file. The 2SK series covers N-channel field-effect transistors in the Japanese designation system, and a…

Indexed as a schematic, this 33.9 KB PDF for the 2SK655 is best read as a transistor datasheet, since 2SK numbers designate N-channel FETs under the Japanese JIS…

PDF datasheet, 89.5 KB, for the 2SC4633 transistor, though the index files it under schematics.

Labelled 2SC4578, the 104 KB PDF is indexed as a schematic, though its name matches a single semiconductor part, so it is probably a datasheet.

Larger than most in this series at 211 KB, the PDF for 2SC4448 may include characteristic graphs alongside the ratings tables.

Reference PDF of 260 KB for the 2SC388ATM transistor, an NPN device in the Japanese 2SC series with an A-grade designation and TM suffix in its name; the suffix meaning…

The file name gives nothing beyond 2SC3460, a Japanese JIS designation in which the 2SC prefix denotes an NPN bipolar transistor.

At 160 KB, this PDF for the 2SB1667 is larger than the other 2SB166x and 167x sheets, perhaps containing more curves or pages.

PDF for the 2SA1487, 38.8 KB, carrying an _E suffix that the name does not explain, possibly an edition or language marker.

For anyone replacing a 2SA1417, this 141 KB PDF gives the component reference in one document, though the index labels it a schematic.

PDF reference for the 2SA1360 transistor, roughly 176 KB. The file is labelled a schematic, but naming it after one part points strongly to a datasheet.

Component PDF for the 2SA1248, 47.6 KB, which the index lists as a schematic. Only the part code appears in the name; under the JIS system, 2SA designates a PNP…

The 2SA1012 PNP bipolar transistor, so identified by its JIS 2SA prefix, is documented in this 216 KB PDF.

Reference sheet in PDF form (150 KB) for the registered semiconductor number 2N6804, catalogued under schematics.

Datasheet-type PDF, 244 KB, for the JEDEC part 2N6036, filed in the schematic category of the index. The name provides only the part number, with no maker or revision.

Datasheet for the 2N3392 in a 296 KB PDF, filed as a schematic. Identical in size to neighbouring 2N3390 to 2N3393 entries, it is probably a shared family document…

PDF datasheet for the 2N3055 at 236 KB, catalogued as a schematic; the a1 ending in the name is not defined and could be a vendor document code or revision.

Datasheet-style PDF for the 1SS385F, 68.1 KB, filed under schematics. The trailing F is part of the part number and may indicate a package or variant of the 1SS385, so…

Listed as a schematic, the 229 KB PDF titled 1B21 carries only a short code and no model, brand or revision, so its subject must be confirmed by opening it.

Short PDF of 130 KB named 274002, a bare number that gives no device, brand or part information.

The 103 KB PDF 62ctq030 is filed as a schematic, yet its name holds only a part-number-style code with no brand, device or board revision.

A short PDF of 53.5 KB, labelled 60CDQ and catalogued as a schematic. No product, brand, board revision or version appears in the name, so it should be opened in a…

The 155 KB PDF titled 15tq060 is listed under schematics, but the name corresponds to the International Rectifier and Vishay Schottky rectifier numbering style.

Here the name gives only the part number 12CWQ03FN, and at 129 KB the PDF is almost certainly a single component datasheet.

PDF schematic labelled SL410, 1.32 MB, with no brand, motherboard number or revision in the file name.

Second copy of a Quanta LV6 archive, matching the other LV6 package at 5.46 MB, so it is likely a duplicate.

Small ZIP archive containing an embedded controller firmware image named simply EC.bin, with no model, board or version given.

Boardview archive for the Huawei MateBook X laptop, compressed as RAR, with no board number or revision stated in the name.

RAR archive for the Toshiba Satellite U920t, naming board FLXOMB1 and the code A3353A, which is probably a board part or assembly number.

Status register value file, 2 bytes, saved by a programmer from a GigaDevice GD25Q64 chip on 1 April 2019. It carries no BIOS data and is not a flashable image.

ZIP archive, 1.29 MB, for the Quanta X81 project, with no brand, revision or contents given in the name.

Windows executable whose name follows HP's SoftPaq convention (sp plus a number). The name does not say which driver, utility or BIOS update it contains or which models…
