A 29.2 KB PDF documenting the 2SD2639 part, catalogued as a schematic. Nothing beyond the type number is stated in the name.

Filed as a schematic, this 53 KB PDF is named after the 2SD1725 part number, so it is most likely a component datasheet rather than a board diagram.

PDF document, 28.7 KB, labelled as a schematic and named 3LP01SP. The name points to an individual semiconductor part code with an SP suffix and gives no device, brand…

Covering the 2SK2865, this 424 KB PDF sits in the schematic category but, judging by its name, is the component datasheet.

Datasheet in PDF form for the 2SK1067, a member of the 2SK family of N-channel FETs, at 144 KB. The file carries no further details in its name.

A 92.7 KB PDF catalogued under schematics but titled only 2SJ228, a JIS-style designation used for P-channel FETs.

The 2SD1198 is the subject of this 56.6 KB PDF, filed as a schematic although the name points to a component datasheet; an _E suffix follows the part number with no…

Datasheet-style PDF of 88.2 KB for the semiconductor 2SC4475, catalogued in the schematic section.

The name of this 156 KB PDF is just the part number 2SC4134, so despite its schematic label it should be the datasheet for that transistor.

PDF component sheet for the 2SC3481, 131 KB in size and catalogued with schematics. The file name holds just the part number; the 2SC prefix is the JIS designation for…

Named after the 2SA1537 transistor, this 41.0 KB PDF sits in the schematic category but should contain the manufacturer data for that part.

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…

PDF reference sheet, 214 KB, for the 2N6282 discrete device, listed as a schematic but most likely a datasheet.

A compact 32.6 KB PDF for the 2N3773, a JEDEC-registered 2N-series transistor; despite the schematic label it is a component datasheet rather than a circuit drawing.

Reference sheet for the 2N2905 PNP silicon transistor, a 55.3 KB PDF placed in the schematic category.

Single-component sheet for the 1SV291, saved as a 73.7 KB PDF and tagged as a schematic.

Datasheet for the 1N4448 small signal switching diode, stored as a 78.8 KB PDF. The 1N4448 is a close relative of the widely used 1N4148, offering fast switching in a…

Covering the 203CMQ080, this 144 KB PDF is most likely a datasheet for a CMQ-series Schottky rectifier rated, judging by the 080 suffix, at 80 V.

A 553 KB PDF called simply 29040, indexed under schematics, which by its number most likely covers a 4 Mbit 29-series parallel flash memory datasheet; the manufacturer…

PDF filed as a schematic under the name 28C256, the widely used 256 Kbit parallel EEPROM part code.

Filed as a schematic, this 251 KB PDF is the datasheet for the Microchip 24LCS21A, a DDC serial EEPROM designed to store EDID data for displays.

A 218 KB PDF covering the 10ETF02, 10ETF04 and 10ETF06 parts, filed under schematics. These names follow rectifier diode numbering of the International Rectifier and…

Circuit diagram in PDF form for the X55C, with an additional RG suffix whose meaning the name does not explain. The file is 1.39 MB and opens in any PDF viewer.

PDF schematic labelled only T43, with no brand, board number or revision given in the name, so the exact platform has to be confirmed against the board itself.

Compal LA-D841P schematic in PDF, compressed into a 2.86 MB RAR; the name gives no brand, model or revision.

Schematic in PDF for the ASUS K53SV notebook; the name does not state the mainboard revision.

Firmware dump for a Micromax 20B22HD-V television built on the CV59L-C23 universal mainboard, marked ok, meaning it was reported as working.

PDF schematic for the Apple logic board 820-3023, packed into a 1.42 MB RAR archive. The name carries no revision letter, so confirm the suffix on the board before…

NexusBV version 0.7.3 in a 7.10 MB zip archive, judging by the name a program for viewing boardview files rather than a document for a specific board.

Part list document 1304-4322 for the F32, revision 2, provided as a 664 KB PDF. No manufacturer or device category appears in the name, so confirm the F32 designation on…
