A 349 KB PDF named for the 2SC2670 transistor and catalogued as a schematic, most likely containing the device datasheet. JIS 2SC numbering identifies NPN bipolar parts.

A 193 KB PDF for the 2SA950, catalogued as a schematic but carrying a JIS semiconductor designation.

Lenovo service file for a Foxconn board coded 661S03, packed as a 1.12 MB RAR. The 661 prefix may point to the chipset generation, but that is not certain, and the name…

Datasheet for the LM50, a single-supply analog temperature sensor whose output includes a fixed DC offset so it can report temperatures below zero without a negative…

2SJ194 is the sole identifier in this 117 KB PDF; in JIS designations the 2SJ series covers P-channel field-effect transistors, so the document should be a part…

A 196 KB PDF named for the 2SC4684 and listed in the schematic category. Its 2SC prefix is the JIS marker for NPN bipolar transistors, so the document is best read as a…

A 128 KB PDF for the 2SC4564, filed among schematics but almost certainly a datasheet, since the name is just a JIS transistor number.

PDF documentation for the 2SC4252, 302 KB, catalogued in the schematic section. No further information such as manufacturer, package or version is carried by the name.

A 200 KB PDF for the 2SC5458, a part in the Japanese 2SC numbering scheme for NPN bipolar transistors, filed here as a schematic.

Transistor number 2SC4824 is all the name of this 141 KB PDF reveals; the index places it among schematics.

Named 2SC5360, this 117 KB PDF concerns a Japanese JIS-registered NPN transistor, the 2SC prefix denoting a high-frequency type.

Covering the 2SC5320, this 124 KB PDF is indexed as a schematic but is almost certainly a datasheet for a single transistor.

English-language edition, judging by the _E suffix, of a document for the 2SB1488 transistor, stored as a 46 KB PDF under schematics but almost certainly a datasheet.

Specifications for the 2SA1963 transistor are expected in this 160 KB PDF, which the index labels a schematic.

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

Archive named only m526, a 2.59 MB ZIP whose name reveals no brand, board number or document type.

Small Toshiba RAR archive, 455 KB, named CD731A. The name gives no laptop model, and CD731A is not a code that can be decoded with certainty, so it may be a project name…

BIOS archive for an X450LD at revision 2.1, almost certainly the ASUS model, though the brand is not stated in the name, packed as a 3.23 MB RAR.

HP 6005 desktop BIOS, an AMD platform, family 786G6, version 01.17, 1.00 MB .rom. The name also notes amdb24 and 2ddr3; amdb24 is not certain, while 2ddr3 likely…

A small 33.3 KB PDF covering the 2SD330 transistor, listed as a schematic though it documents a single discrete part. The name carries no other details.

Reference sheet in PDF form for the 2SK2349, sized 54.7 KB and listed in the schematic category.

A small 31.5 KB PDF identified only by the part number 2SK374. Under JIS numbering the 2SK series covers N-channel FETs, so the content is almost certainly a short…

A small 30.6 KB PDF for the 2SC4637LS. The LS suffix appears to denote a particular package or lead variant of the 2SC4637 NPN transistor, so check the outline drawing…

A 155 KB PDF for the 2SC5245 transistor, catalogued as a schematic but by its name almost certainly a component datasheet.

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 103 KB PDF named only after the part 2SC3992, indexed as a schematic but in practice almost certainly a transistor datasheet.

A 41.5 KB PDF covering the 2SC4808, a part number in the JIS 2SC series used for NPN bipolar transistors.

The 2SB1320A, a suffixed variant of the 2SB1320, is described in this 56.6 KB PDF filed under schematics.

Covering the 2SA1242, this 212 KB PDF carries only the part number in its name, so it is best treated as the component datasheet despite the schematic label.

Filed under schematics, this 65.3 KB PDF is named only for the 2N5191 part number, so it is almost certainly a component datasheet rather than a board drawing.

Datasheet-style PDF for the 10CTQ150, about 135 KB, listed in the index as a schematic.

Small zip archive listed as a schematic, named only M546B. The name gives no brand, board revision or document details, so the contents have to be checked before use.

Fourth chapter of a Spanish cellular-phone course, dealing with cloning or unlocking, saved as an 863 KB PDF.

A 6.24 MB ZIP archive named only UC6, which tells nothing certain about the device, board number or contents.
