Largest of this group at 382 KB, this PDF documents the 2SK1930, an N-channel field-effect transistor under Japanese JIS numbering.

Larger than most in this series at 254 KB, this PDF documents the 2SC4497 NPN bipolar transistor, the 2SC prefix being the JIS designation.

Named simply 2SC4427, this 109 KB PDF documents a single semiconductor rather than a complete board.

At 411 KB, this PDF for the 2SC5717 is one of the larger documents in the set and is probably a complete datasheet with graphs.

Another 469 KB PDF from the 2SC48xx range, this one labelled 2SC4842. The 2SC prefix in JIS semiconductor numbering denotes an NPN bipolar transistor, so despite the…

At 217 KB, this PDF for the 2SC3673 is one of the larger documents in the 2SC367x group and is indexed as a schematic.

Datasheet-style PDF for the 2N5089, listed in the schematic category at 97.4 KB. The name gives just the JEDEC part number, with no maker or revision stated.

Reference PDF for the 1SV285, about 70.4 KB, catalogued as a schematic. The 1SV prefix marks a variable-capacitance diode, so this should be a manufacturer data sheet.

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.

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

Archive with the uninformative label H0222-SE, 401 KB in RAR format, giving no device brand, model or content type.

PDF for the bq24780S, a Texas Instruments battery charge controller used in notebooks; though tagged as a schematic, the 1.03 MB file is most likely the datasheet.

Datasheet PDF, 137 KB, describing the PC1602LRS-HSO-H LCD module, a 16x2 character display by its 1602 designation.

A 513 KB datasheet in PDF, filed under literature code SDLS212 without any part number in the name.

PDF datasheet of 343 KB identified only by literature code SDLS205. The specific component is not named in the file name; the SDLS code pattern is associated with Texas…

PDF datasheet, 255 KB, labelled SDLS177 with no device description in the name. Texas Instruments documents many standard logic ICs under SDLS literature codes, so check…

PDF datasheet from Texas Instruments identified only by its literature code SDLS138, about 311 KB.

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

Zip archive, 734 MB, labelled as Microsoft Office 2007; the name does not indicate edition, language or whether a licence key is included.

Large 27.9 MB archive for Quanta motherboard DA0R33MB6E0, revision E. A size like this usually points to several documents, such as a full schematic set with boardview…

Package for Wistron board 11253-2, second revision, with 4ST06 in brackets, likely an OEM part number.

PDF of 458 KB for the LTA216AT01, a code that reads as an LCD panel model; at this size it is probably a specification sheet rather than a full schematic.

PDF of 2.59 MB for the LM220WE1, a code that corresponds to an LCD panel model; the name says nothing more, so the content is likely the panel specification.

PDF schematic labelled N76VM, an ASUS N76 series board designation, with an RG suffix whose meaning is not clear from the name.

PDF datasheet for the Texas Instruments TPS25810, a USB Type-C downstream-facing port controller with an integrated power switch.

Archive for the MSI MS-7623 motherboard, 549 KB in RAR format. The name gives no revision, so open it and check whether the documents specify one, then compare with the…

IBM-labelled RAR archive of 1.58 MB named Yukon, which appears to be an internal project or platform code name, not a retail model.

Board-level documentation for the IBM ThinkPad T42, packed into a 1.04 MB RAR file. The name gives no planar number, revision or content type, so check inside whether it…

RAR archive of 2.45 MB labelled Dell 1530, most likely the XPS M1530, although the name states only the number and no board code or revision.

RAR archive of 1.92 MB named Dell 1427 with a trailing _1, which may indicate a second copy or part. No board number, revision or contents are given in the name.

Zener mono power amplifier rated 500 W, documented in a 952 KB PDF. The name gives no revision or further details, so verify the content on opening, which may include…

RAR archive labelled 2PESV-03, about 1.57 MB, with no brand, model or file type stated.

RAR archive of 10.1 MB named A500H SM, where SM most likely stands for service manual, though the brand and device are not stated in the name.

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…

RAR archive of roughly 567 KB for the HP Compaq Presario CQ20 notebook. The name gives no board number, ODM, revision or document type, so open the package to see…

Dell Inspiron 1318 archive, misspelled Inpiron in the name, size 1.87 MB. Only the model is given, without a board code, ODM name or revision, so open the RAR to see…

Compal board documentation for the project code-named Comaneci, revision X05, packed as a 1.24 MB RAR archive.

Apple logic board 820-3330 revision B, delivered as a RAR archive of about 1.97 MB. No model or content list appears in the name, so inspect the extracted files first…

RAR package, 1.53 MB, for Apple logic board 820-2807. Besides the number, the name gives no model, revision or content details; a second archive of identical size exists…
