Patched BIOS image for a Dell Latitude 7330, about 10.1 MB packed in a RAR archive. The name does not say what was patched, but such files are usually modified to clear…

Repair guide for the P553UJ notebook, abbreviated RG in the name, in a 726 KB PDF. These guides normally combine board photographs, component locations, typical voltage…

Lenovo 300e 2nd generation BIOS image, 16 MB in raw BIN form, labelled old and with an enrol or ast note that the name does not fully explain.

Small 65.1 KB PDF reference for the HEF4008BP, a CMOS logic device from the HEF4000 series that the 4008 number identifies as a four-bit full adder; the BP suffix…

PDF of 426 KB named for the 2SK2842 part number and filed in the schematic category. Because the 2SK prefix denotes an N-channel field-effect transistor in JIS…

PDF file of 314 KB for the 2SK2776, indexed under schematics. Since the 2SK prefix designates an N-channel field-effect transistor in the Japanese JIS system, the…

Covering the 2SK2733, this 413 KB PDF sits among schematics but is most likely the device datasheet, since 2SK is the Japanese JIS prefix for N-channel field-effect…

A 134 KB PDF for the 2SK2460N, catalogued as a schematic but almost certainly a datasheet for a discrete transistor, since 2SK numbers under the Japanese JIS system…

The 2SK2350 is identified here only by its part number, in a 417 KB PDF catalogued as a schematic.

Reference sheet for the 2SJ620 in PDF form, 345 KB, listed in the schematic category. The 2SJ prefix follows the Japanese JIS scheme for P-channel field-effect…

Datasheet-like PDF, 42.5 KB, for the 2SJ583LS and filed as a schematic. Japanese JIS designations starting with 2SJ belong to P-channel FETs, and the LS suffix points to…

Part number 2SC4223 is all the file name gives, so this 93.9 KB PDF is best treated as a datasheet for that component rather than a circuit schematic.

PDF documentation for the 2SC4793 transistor, at 173 KB larger than most files in this series and probably a fuller datasheet with characteristic curves.

Datasheet in PDF form, 289 KB, for the 2SC3547B, filed with schematics. The B suffix marks a variant of the 2SC3547; the name alone does not say whether it denotes a…

A small 44.6 KB PDF named 2SC5310, filed under schematics though the title is a transistor part number.

Filed as a schematic, this small PDF of 60.3 KB is named only with the part code 1T410 and gives no device, brand or board number.

Part number 1SS362 is all the file name reveals; the 69.1 KB PDF should be the specification sheet for this small-signal silicon diode, as the JIS 1SS prefix indicates…

Only 34.2 KB, this PDF is named 1N957, a JEDEC 1N diode designation, and is better described as a component datasheet than a schematic.

Catalogued as a schematic, this 80.2 KB PDF carries the code 249NQ135, which looks like a power diode or rectifier module part number, so a datasheet is the likely…

Titled 4GBL series, this 104 KB PDF is filed as a schematic but names no device, board or revision.

Named 100bgq045, this 85.8 KB PDF is filed among schematics, though the title reads as a power rectifier part code rather than a board number, and no device, brand or…

Catalogued as a schematic, this 432 KB PDF named 29040l most likely documents a 4 Mbit 29-series parallel flash memory, the l suffix probably marking a low-voltage or…

Listed under schematics, this 116 KB PDF is named 85hf and says nothing about brand, board or revision.

A 48.5 KB PDF in the schematic category, named 75SLQ045. The name carries no model, brand or board number and resembles a discrete power semiconductor part code, likely…
