Unlabelled ZIP archive of roughly 5.6 MB whose generic name gives no hint of the device, board or file type inside.

Boardview for the Apple A2159 MacBook Pro, logic board 820-01598, compressed into a 183 KB zip.

BDV boardview for the Gigabyte GA-H61M-S, an Intel H61 microATX desktop board, packed in a 396 KB RAR archive.

Small boardview archive, about 92 KB, for Wistron board 18730-1M, with no laptop model given in the name.

Schematic PDF named only CD731a, about 526 KB, with no brand, model or revision information in the name.

ZIP archive holding a boardview for the ASUS S451 laptop, revision 2.0, with FZ as an extra marking in the name whose meaning is not stated.

Boardview for the Lenovo V130-15IKB, whose motherboard is the Wistron LV315KB design numbered 17807-SC, delivered as a ZIP.

Reference PDF for the HCF4050B, a non-inverting hex buffer from the CMOS 4000 family, as the file name itself states.

PDF reference, 218 KB, for the LA7286, an IC from the LA series, a prefix associated with Sanyo linear integrated circuits.

Component datasheet covering the IRFP240 MOSFET, supplied as a 104 KB PDF readable in any PDF viewer.

Datasheet for the IRF510 N-channel MOSFET, a 97.7 KB PDF. The document should cover ratings, transfer and output characteristics, capacitances and the TO-220 pinout.

PDF titled only with the part number D304X, about 489 KB, filed as a schematic. The name gives no further detail on device type or manufacturer, so the contents are most…

Manufacturer datasheet for the BD139 transistor, with the name indicating the ST (STMicroelectronics) version, supplied as a 152 KB PDF.

A 53.4 KB PDF covering the 2SD2614 transistor, catalogued as a schematic although the name points to a single-part datasheet.

The 2SD2648 is covered by this 29.0 KB PDF, indexed as a schematic but in practice a single-device reference.

Component reference for the 5LP02C, a 42.3 KB PDF that the index lists as a schematic. The name carries just the part code, where the LP letters appear to mark a…

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

A 28.0 KB PDF classed as a schematic whose name, 3LP01C, reads as a component part code ending in C. The file name gives no device, board number or manufacturer.

Named only 2sd1897, this 35.6 KB PDF is listed as a schematic, yet the name is a JIS transistor number, so it is very likely a compact datasheet.

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.

Brief 28.4 KB PDF for the 2SK2864, indexed as a schematic; its small size points to a one or two page datasheet or summary. The name gives only the part number.

A very small PDF of 23.8 KB named for the 2SK2797, filed under schematics. The 2SK prefix follows the JIS naming convention for N-channel field-effect transistors, so…

Short PDF, 43.6 KB, named after the 2SK2791 and listed as a schematic. The 2SK prefix marks an N-channel FET under the JIS scheme, so this is likely a compact datasheet.

PDF reference, 35.6 KB, for the 2SK2276, a Japanese JIS-registered device where the 2SK prefix indicates an N-channel field-effect transistor.

Only the transistor number 2SJ259 appears in the name of this 99.0 KB PDF. JIS coding uses 2SJ for P-channel FETs, which suggests a datasheet even though the file is…

PDF document for the 2SD1205 transistor, listed in the index as a schematic but almost certainly a part datasheet; the trailing _E in the name is a suffix whose meaning…

RAR archive of 5.61 MB for the OPPO R15 smartphone. Only the model appears in the name, so the contents, whether schematics, board layouts or both, need to be checked…
