Short PDF of 50.8 KB for the 2SC1509, with an _E suffix in the file name, listed in the schematic section.

Indexed as a schematic, this 41.7 KB PDF carries the part number 2SC1360, an NPN transistor according to Japanese JIS numbering, which points to a datasheet for a single…

An 85.0 KB PDF covering the 2SA1965, whose 2SA prefix under JIS rules marks a PNP bipolar transistor.

Part documentation for the 2SA1932, supplied as a 197 KB PDF. The file is listed as a schematic, but the name holds only the component number, so treat it as a…

Component sheet for the 2SA1866 PNP bipolar transistor, stored as a 55.4 KB PDF. The 2SA prefix follows Japanese JIS conventions for PNP devices.

Datasheet PDF for the 2N7002, with an r2 tag in the name that most likely marks the second revision of the document; size 94.4 KB, listed in the schematic category.

Very small PDF of 26.3 KB named with the part number 2N5639 and nothing else. Listed as a schematic, it is most plausibly a short datasheet, since 2N codes are JEDEC…

A 58.4 KB PDF that covers two JEDEC part numbers together, the 2N5088 and 2N5089, with a Sam tag in brackets whose source is not spelled out in the name.

PDF data sheet of 47.6 KB for the 1T411 transistor, filed in the schematic category. Following the Soviet designation scheme, the 1T prefix denotes a germanium…

A 57.0 KB PDF listed as a schematic and named 1SV216, followed by an underscore that appears to be a naming leftover.

Indexed as a schematic, this 68.4 KB PDF takes its name from the diode number 1SS372 and gives no device, board or brand information.

A 126 KB PDF filed under schematics, though its name, 1SS269, points to a semiconductor part rather than a circuit board.

Datasheet in PDF form for the 1N4936GP, a glass passivated version of the 1N4936 fast recovery rectifier, about 45.7 KB.

No device or board appears in the name 161cmq, which instead looks like a dual Schottky rectifier family code; at 47.0 KB this PDF is probably a short datasheet, though…

At 43.6 KB, this PDF titled 152cmq030 is listed among schematics, yet the name is a rectifier part code for a common-cathode Schottky pair, commonly a 30 V grade.

Catalogued as a schematic, this 203 KB PDF named 87cnq020a is most likely a datasheet for a low-voltage dual Schottky rectifier module, the 020 typically denoting a 20 V…

Indexed as a schematic, this 54.4 KB PDF is named 50HQ, a short series-style code with no laptop model or board number.

Named 28C17A, this 138 KB PDF is catalogued as a schematic but the code points to a 16 Kbit class parallel EEPROM in the 28C series, A revision.

Datasheet in a 106 KB PDF for the 27c256, a part number in the common 27C CMOS EPROM family, although the catalogue lists it as a schematic.

This 112 KB PDF in the schematic section is named 20ETF-S-HV. The name lists no laptop model, board number or revision, only a part-style code with S and HV suffixes.

Small RAR archive, 45.6 KB, labelled for the ASUS A7K laptop. The name gives no indication of whether it contains a schematic, a parts list, a boardview or firmware, and…

Schematic PDF for the Wistron-numbered Rayleigh SLS board 14302-1M, with the code 06B08 also listed.

PDF schematic for the Compal LA-G714P motherboard. The name carries no model or revision details, so confirm the board number on the PCB.

Archived BIOS firmware for the Acer Aspire One 753 netbook, listed as AO753, 1.54 MB compressed.
