Schematics for the Nokia N8 in a 6.23 MB PDF file. The name lists no hardware revision, so compare the board version on the PCB before trusting component numbering.

Schematic package for the Nokia 6600 smartphone, presented as a 3.25 MB PDF. The diagrams cover the circuitry that a repair technician needs for board-level work: power…

Nokia 5120 schematic diagrams in a 432 KB PDF. Only the model name is provided, with no board number or revision.

Schematic diagrams for the Nokia 1220 handset, packed in a 564 KB PDF; no revision is given in the name.

Circuit diagram in PDF form for a laptop identified only as U6V, about 950 KB in size. The file name states no motherboard number, revision or manufacturer, so the exact…

Laptop schematic marked only with the project code M841 and DVT, the design validation test stage, without brand or board number in the name.

Maxim MAX1772 datasheet, a short 358 KB PDF with nothing in the name beyond the part number. Consult the first page for its exact function, ratings and package.

Reference PDF of 27.6 KB for the component 5HP01S, filed among schematics although it describes one discrete part.

PDF of 41.6 KB, catalogued as a schematic and named 3LN02M, which looks like a semiconductor part number with an M suffix rather than a board code.

A 30.6 KB PDF labelled with the JIS part number 2SK3488 and filed in the schematic category, though the content should be a component datasheet.

Part reference 2SJ508 is all the name provides for this 136 KB PDF, categorised as a schematic.

The 90.8 KB PDF is named only 2SJ273, a part number in the JIS series used for P-channel FETs.

The 2SJ225 is the only information this 91.8 KB PDF name provides; the 2SJ prefix in Japanese semiconductor numbering identifies a P-channel field-effect transistor.

Part documentation for the 2SD1196 in a 139 KB PDF, placed in the schematic category but evidently a component datasheet given its name.

Here is a compact 94.6 KB PDF named for the transistor type 2SC4660. The name points to the part itself rather than any board or appliance.

The name of this 176 KB PDF consists only of 2SC3790, a JIS-style part number in which 2SC denotes an NPN transistor.

A 58.1 KB PDF labelled as a schematic and named after the 2SC1215, an NPN transistor by Japanese JIS naming, so it should be the datasheet for that discrete part.

A compact 19.1 KB PDF for the 2SA1580, small enough that it is probably a one- or two-page summary sheet. No other details are present in the name.

An 86 KB PDF covering the 2SA1896, a PNP bipolar transistor under the Japanese JIS 2SA designation.

A 52.2 KB PDF in the schematic listing, labelled simply 2N6487, a part number from the JEDEC 2N discrete semiconductor series.

Filed as a schematic, this 271 KB PDF is named after the discrete part number 2N5684 with an unexplained RE suffix, which may indicate a reissued edition.

Switching-diode reference named 1SS184, saved as a 69.3 KB PDF and filed by the index as a schematic. The underscore in the name carries no extra detail.

Named 35scgq045, this 70.6 KB PDF is grouped with schematics, but the name suggests a discrete component code and carries no device, brand or revision information.

A 163 KB PDF catalogued as a schematic, though the name points to the 28LV256, a 256 Kbit low-voltage parallel EEPROM, so it is most likely a datasheet.

A compact 77 KB PDF filed as a schematic, named 24WCXX, which refers generically to the Catalyst Semiconductor 24WC series of I2C serial EEPROMs; the name gives no…

Indexed under schematics, this 87.3 KB PDF carries the code 20ETS-FP and does not mention a laptop model, board number or revision.
