Very small schematic PDF, only 25.3 KB, labelled for the Nokia 6610 and 7210, which share much of their hardware; the name uses skemat instead of schematic and adds a…

Vietnamese-language repair handbook covering ThinkPad T40 to T43 models; the title translates roughly as repair manual.

Schematic for the Sony VAIO VGN-FJ series, designed by Quanta under project code RD1, revision 1A.

PDF schematic covering the SM7225 processor, 1.52 MB, with no handset model or revision mentioned. Open it in a PDF reader to search net names and pin functions.

Schematic archive named only M33, with no brand given, a 940 KB ZIP. The name is too brief to identify the device reliably; it may be a phone model code, but that is not…

CD4017 document in PDF form, 81.0 KB, for the CMOS decade counter with ten decoded outputs.

Compact 42.5 KB PDF for the 2SD1824, carrying an E suffix in the name that is not otherwise explained.

Datasheet for the 4N38 optocoupler, marked as revision 2 in the name and supplied as a 294 KB PDF filed among schematics.

Datasheet for the 2SD2117, filed as a schematic but actually a component specification in PDF form, about 67.5 KB.

An 88.2 KB PDF titled 2SD1884, indexed in the schematic section but, judging by the bare part number, a datasheet for that transistor.

The 2sd2394 NPN transistor is covered by this 53.3 KB PDF, which the index files as a schematic.

The part number 2sk2210 is the sole clue to this 33.6 KB PDF, catalogued under schematics but most likely a short component datasheet.

The 2SK2101 part number is followed by an extra 01mr suffix in this 175 KB PDF. The name does not explain that suffix, which could be a document code or revision.

Only the part number 2SK1897 identifies this 97.1 KB PDF, which the index places among schematics.

For the 2SK1427 N-channel FET, this 101 KB PDF sits in the schematic section of the index but most likely contains a datasheet.

PDF of 104 KB for semiconductor 2SK1421, classed as a schematic in the index. JIS numbering places 2SK parts in the N-channel FET family; maker and package cannot be…

Manufacturer documentation for the 2SK1066 transistor, a 303 KB PDF. Under JIS numbering, 2SK parts are N-channel field-effect transistors, so despite the schematic…

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…

The 2SK657 datasheet, filed as a schematic, is a 35.7 KB PDF; the 2SK prefix identifies an N-channel FET in the Japanese semiconductor numbering scheme.

Listed as a schematic, this 31.1 KB PDF is named for the 2SJ594, a format typical of an individual component datasheet.

A 379 KB PDF covering the 2SJ304. The file name holds only the part number, with no reference to a product.

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…

Datasheet document, by all indications, for the 2SJ189, a JIS-registered P-channel FET, held as an 83.5 KB PDF in the schematic section.

A 144 KB PDF whose name is just the part number 2SD1190, filed as a schematic but in practice a transistor datasheet.

PDF reference of 143 KB named only for the 2SC4729. The 2SC prefix is the JIS code for an NPN bipolar transistor, so the catalogue label of schematic most likely stands…

The 2sc4725 is the subject of this 56.8 KB PDF, categorised as a schematic. Since 2SC is the JIS designation for NPN bipolar transistors, the document is most probably…
