Part reference for the 2SA1291 in PDF form, 40.8 KB. Filed as a schematic, but the name holds nothing other than a component code, and 2SA under the Japanese JIS scheme…

The name points to the 1SV248 device, and the 60.4 KB PDF is filed as a schematic. Because 1SV is Toshiba's designation for variable-capacitance diodes, the document is…

A 69.5 KB PDF titled with the component number 1SS367, with nothing in the name about a device or board.

A 21.1 KB PDF carrying the part number 1n6768, best understood as a datasheet for a JEDEC 1N-series device rather than a board schematic.

Labelled 1n6762, this 17.2 KB PDF appears to be a datasheet page for a JEDEC 1N-numbered device rather than a circuit diagram.

PDF document of 123 KB titled only 274001, an uninformative numeric name that does not identify the manufacturer or what is covered.

Tiny 14.4 KB PDF titled 25C020, filed under schematics with no brand, board or device named.

PDF of 66.0 KB named 25C03, indexed under schematics, with no brand, board or device information in the name.

PDF schematic whose name, KL2D, is only a short project or board code, with no brand, revision or model given.

Quanta BLBD schematic, a 973 KB PDF. The name holds only this code, with no revision or laptop model, and the exact meaning of the BLBD suffix is not stated, so it could…

Troubleshooting chapter, 2.39 MB PDF, with no device or brand named in the title, so the covered model must be confirmed by opening it; it likely belongs to a split…

Schematic PDF for the Gigabyte GA-H87-HD3, revision R102, which appears to be an earlier issue than the R11x drawings for the same board.

Generic file named index2, a very small 20.9 KB PDF catalogued as a schematic. The name reveals nothing about the device, brand or board, so open it and identify the…

Schematic in PDF format labelled IBM YUKON, where Yukon appears to be an internal platform or project code name rather than a retail model.

IBM ThinkPad A30 schematic diagram in PDF form, roughly 986 KB in size. No motherboard number or revision appears in the file name, so confirm the board markings match…

GC-RP64LED revision 1.0 schematic in PDF form, about 182 KB and evidently another copy of the same drawing.

PDF schematic document for the Samsung SM-G130E, with no other details in the name beyond the model code.

Schematic PDF named NL3 E with a 0430 1615 date and time stamp, suggesting a dated working revision of an engineering design.

Small 178 KB PDF schematic for the Lenovo IdeaPad 330S, covering the MIO-KB part; this appears to be a daughter board or keyboard I/O section rather than the main board…

Quanta UM3B schematic in PDF form, about 2.9 MB, with no brand, model, board number or revision in the name.

PDF schematic of the Jetway 695AS motherboard, about 420 KB, with no revision mentioned in the name.

Schematic PDF named only by the code 00001956E, giving no brand, device or board number.

Schematic covering the HP EliteBook 8530w and 8530p, two related models that the file name shows sharing one document.

Small 9.66 KB PDF for Sony devices titled as a blink code reference, presumably listing the meaning of LED flash patterns shown on failure.

Laptop schematic labelled Z94RP, revision 1.2, supplied as a 2.50 MB PDF. The name gives no brand or board number beyond this project code, so confirm the details on the…

ASUS repair guide for the K53SV notebook, provided as a 593 KB PDF and filed as a schematic.

A compact 106 KB PDF covering the 2SK2919 transistor, indexed as a schematic though the name points to a manufacturer datasheet.

PDF of about 295 KB for the 2SK1827. In JIS part numbering, 2SK stands for an N-channel FET, so the content should be a datasheet rather than a board-level drawing.

Compact 125 KB PDF for the 2SC5091FT, an NPN bipolar transistor numbered under the Japanese 2SC scheme, with the FT suffix as part of the name; its exact meaning is not…

At only 24.2 KB, the 2SC3989 PDF is a compact document, probably a short datasheet or summary page for this JIS-numbered NPN bipolar transistor despite being indexed as…

Indexed as a schematic, this 95.8 KB PDF carries only the designation 2SC4821. In the JIS system the 2SC prefix denotes an NPN transistor, so the content is most likely…

Compact 102 KB PDF for the 2SC3090 transistor, indexed under schematics. The name carries no detail beyond the part code.

Datasheet-style document for the 2SB1424, indexed as a schematic and supplied as a 102 KB PDF. Nothing beyond the part number is stated in the name.

Datasheet-style PDF, 317 KB, covering the 2SA1316 transistor even though the index type reads schematic.

Part document for the 2SA817A, provided as a 174 KB PDF with no board or equipment model in its name.

A 61.0 KB PDF for the 2N4125 part number, the plain-named counterpart to an RE variant also present in the index.

Here the 2N4123 is covered by an 83.6 KB PDF, the plain-named version alongside an RE-suffixed file for the same number.

A PDF document for the 1SV215 part, catalogued as a schematic but most likely a component data sheet.

The name gives nothing beyond 1N3085, a number in the JEDEC 1N series reserved for semiconductor diodes, so this 86.0 KB PDF is best treated as a part datasheet despite…

Very short 20.1 KB PDF for the part 27C256-12A, catalogued as a schematic. The number belongs to the 27C EPROM family, and the -12 suffix normally reflects the…
