Very small PDF schematic named only 4kw2, probably a second sheet or variant of a 4 kW power amplifier design, though the name gives no further detail.

PDF schematic for the Apple iPhone XS Max logic board, 1.45 MB. The name gives no board number or revision, so check it against your phone's logic board before relying…

Board layout PDF for the Motorola XT1543 (Moto G third generation family), the companion to its electrical schematic; the name spells layout as layoult.

At 180 KB, this PDF named 2SD2449 is larger than most of its neighbours and is catalogued as a schematic.

PDF reference for part 2SK1833, around 34.6 KB. Following JIS rules, 2SK identifies an N-channel FET, and the document is likely its datasheet despite the schematic…

The 2SK1736 is documented in this 92.6 KB PDF. Under JIS designations, 2SK means an N-channel FET, so the file is almost certainly a component datasheet despite its…

34.2 KB PDF for the 2SK1255 N-channel MOSFET, listed under schematics in the index although it is a single-component sheet.

The 2SC5473 has its own 38.2 KB PDF, carrying an _E suffix that probably indicates the English-language version.

Labelled 2SC5351, the 191 KB PDF refers to a JIS-registered NPN transistor, where the 2SC prefix indicates a high-frequency type.

Datasheet PDF, 24.1 KB, for the 2SB772L variant from UTC, likely Unisonic Technologies.

Component datasheet for the 2SA1803, provided as a 179 KB PDF and indexed with schematics. The 2SA prefix places it among PNP bipolar transistors under the JIS standard.

Part code 1N758A is all the name provides; it matches JEDEC diode numbering with an A suffix, pointing to a component datasheet of 50.3 KB rather than a board schematic.

Indexed as a schematic, this 50.3 KB PDF is titled 1N757A, a JEDEC 1N diode number with A suffix, so it almost certainly holds a part datasheet.

A 126 KB PDF catalogued as a schematic and labelled 5THZ52, without any device, board number or revision.

Named 60CKQ045, this 304 KB PDF is one of the larger files in its set and is filed as a schematic.

At 287 KB this PDF for the 2SK1875 is larger than its neighbours, which may mean extra graphs or pages, though the name says nothing more than the part number.

Only the part number 2SC3361 appears in the name of this 129 KB PDF, so no equipment or board can be identified from it.

Named after part 2N5485, this 755 KB PDF has no board, device or revision details. It shares its size with the 2N5484 and 2N5486 entries, so it is likely the same family…

Short PDF datasheet, 42.1 KB, for the 1N6098 diode, indexed in the schematic section though it covers one discrete component.

A 72.5 KB PDF identified only by the code 45L and indexed under schematics, with no device, brand or revision stated.

This 50.1 KB PDF, labelled 30SCLJQ030 and catalogued as a schematic, most likely documents one discrete rectifier rather than a circuit board, based on its part-number…

Filed as a schematic, this 168 KB PDF is identified only by 20L15T. It gives no brand, model, board number or revision, so its exact subject is unclear from the name…

Document for the KB9012QF, an ENE embedded controller widely used on laptop motherboards.

Lenovo 3000 N100 schematic, a 875 KB PDF that appears to be a second copy of the same document, given the identical size and the (2) suffix in its name.

Disassembly and reassembly guide for the Samsung SM-A325M, a 1021 KB PDF from the service manual.

Electrical part list PDF of 387 KB with no model, brand or board number in its name, so the device it covers has to be confirmed by opening the file.

Main document for the subwoofer 7294 design, version 1.1, a 138 KB PDF without a further descriptor in its name.

Mirrored version of the Apex AX 20 copper-side layout, a small 62.3 KB PDF. The reversed image is meant for toner-transfer or photoresist methods, where the pattern must…

Persian-language PDF whose title translates roughly as how to test electronic components.

PDF titled in Spanish as a software course, catalogued under schematics but almost certainly training material rather than a circuit diagram.

Sony training material in PDF describing the WAX2T LCD TV chassis. Training guides usually explain block diagrams, board functions, signal flow, power sequencing and…

Principle block diagram for the Xiaomi Redmi 3A, titled in Chinese, supplied as a compact 193 KB PDF.
