Small 27.3 KB PDF for part 5LN02C, listed as a schematic though it is evidently a discrete-device datasheet.

A 171 KB PDF for the 4N39 and 4N40 optocouplers, listed under schematics but in practice a component datasheet.

A 90.1 KB PDF named after the 2SD1877 semiconductor and filed as a schematic, although its content is expected to be a component datasheet.

A compact 30.1 KB PDF for the 2SK2682LS. The base 2SK2682 follows JIS numbering for N-channel field-effect transistors, while the LS suffix marks a variant, often a…

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

The 2SK1747 is the subject of this 184 KB PDF. Japanese JIS designation 2SK means an N-channel field-effect transistor, so the file is probably the manufacturer…

A 31.0 KB PDF for the 2SJ597, stored in the schematic category although it is named like a single-part datasheet.

An 88.9 KB PDF for the 2SD1247, indexed as a schematic although the name identifies a single semiconductor.

Compact UTC datasheet, around 14 KB, for the 2SD880 NPN transistor from Unisonic Technologies.

Component datasheet for the 2SD638 NPN transistor, roughly 45 KB in PDF format and catalogued with schematics.

Close in number to its neighbours, 2SC4645 is another JIS-coded NPN transistor, and this 147 KB PDF is probably its datasheet.

Datasheet PDF, 52.4 KB, for the 2SC5574, with the type number written in lowercase in the original name.

The 2SC4108 is the only detail this 94 KB PDF name provides, and the index files it as a schematic.

Covering the 2SC3775 NPN transistor, this 125 KB PDF belongs to a run of JIS-numbered 2SC part documents filed under schematics.

For the 2SC5305? No: this 94.6 KB PDF covers the 2SC3705, an NPN bipolar transistor by its JIS designation, and is indexed under schematics.

Short PDF of 21.2 KB covering the 2SA1575, probably a brief part datasheet despite the schematic label. The name contains no device or manufacturer information.

The 2SA1352 is the only identifier in this 149 KB PDF name, so treat it as the transistor datasheet even though the index calls it a schematic.

PDF reference for the 2SA1968, 91.3 KB, indexed as a schematic though the bare part-number name points to a transistor datasheet.

A 67.7 KB PDF indexed under schematics and named 1SV233, with nothing else identifying a product or board.

The 1SV308 is covered by this compact 69 KB PDF, filed among schematics. 1SV is the JIS diode designation that Toshiba applies to its varactor range, used where…

At 616 KB, 1B31.pdf is the largest of the 1B-coded files and is listed as a schematic, yet its name says nothing about device, maker or board revision.

This 145 KB PDF, filed under schematics, carries the name 85epf08 and nothing about brand or board.

Named 85epf02, this 143 KB PDF is listed as a schematic without any manufacturer, model or revision.

The name 81CNQ035A on this 233 KB PDF identifies a rectifier part code in the International Rectifier dual Schottky family rather than a board, so although it is filed…

Catalogued as a schematic, this 117 KB PDF is named 400DMQ035 and states no device, brand or revision.

The code 60EPS08 is the only information in the name of this 68.1 KB PDF, filed among schematics. There is no device model, brand or board number to go on.

Small 83.6 KB PDF for a part labelled 27c8000i, listed under schematics although the number fits the 27C CMOS EPROM family.

Schematic archive for the model code A145F, a small 606 KB zip whose name carries only that identifier.

PDF document covering the Intersil ISL6259 battery charger controller, labelled as charging IC material.

UL50AT circuit diagram supplied as a 1.23 MB PDF. The file name gives only the model code, without brand, mainboard number or revision, so compare the schematic title…

Fourth PDF in the TH32A410H schematic series, 6.62 MB with a -4 suffix. All four files in the set share this exact size, so they may be copies of one manual rather than…

Schematic for the Gigabyte GA-E350N motherboard, revision 3.0 according to the R30 tag, packed as a PDF inside a RAR archive.

Lenovo ThinkPad T440p document, labelled SOVP with V101, EC009 and 0815, which likely refer to a version, an EC reference and a date code, though the name does not…
