BIOS dump for the Samsung NP730U3E, project MIRANDA13-I, on the Samsung mainboard BA41-02234A at revision 1.1. Archived as a 3.55 MB rar file.

BIOS image of 8 MB labelled 9010 and marked OK, which suggests a dump reported to be working, though the brand and board are not stated.

Output image for the Lenovo ThinkPad X1 Carbon 6th Gen, judging by the name, stored in a 5.73 MB RAR; outimage usually means a processed binary saved from a programmer…

Firmware archive named only V301, which may be a version number; no brand, model or board is given, so the purpose has to be worked out from the contents.

An 88.0 KB PDF for the 2SD1838, a Japanese-registered NPN bipolar transistor, best treated as a datasheet even though it is indexed as a schematic.

Datasheet for the 2SD2271 transistor, a 219 KB PDF and one of the larger files in this 2SD group, so it probably includes detailed characteristic curves.

A 143 KB PDF catalogued as a schematic, covering the 2SD1801 semiconductor part. Under the Japanese JIS numbering system the 2SD prefix marks an NPN bipolar transistor…

Reference sheet for the 2SD2116 NPN transistor, supplied as a 74 KB PDF. Its name follows the Japanese JIS 2SD convention and carries nothing beyond the part number.

Reference document for the 2SD1662 transistor, 137 KB, PDF format, placed in the schematic category.

The 3SK304 is covered by this 25.9 KB PDF, listed as a schematic though it is expected to be a component datasheet.

PDF reference for the 2SK2993 transistor, 424 KB. The file name carries only the part number, which under the JIS scheme denotes an N-channel field-effect transistor, so…

Very small 26.9 KB PDF for the 2SK2951, likely a short datasheet or summary page given its size.

A 134 KB PDF identified solely as 2SK2219, placed in the schematic category but most likely a transistor datasheet.

This 96.1 KB PDF is named 2SK2161 and placed with schematics, but a part-number title like this usually signals a single-device datasheet.

Listed among schematics, this 97.3 KB PDF is named for the 2SK1887. Japanese JIS designations starting 2SK belong to N-channel field-effect transistors, so expect…

PDF of 101 KB for the 2SK1849 transistor, listed with schematics. In JIS numbering the 2SK prefix identifies an N-channel FET, so this should be the device datasheet…

Named only 2SK1463, this 121 KB PDF is grouped with schematics but concerns a discrete part: the Japanese 2SK prefix means an N-channel FET.

A small 98.7 KB PDF about the 2SK1416, catalogued under schematics but most likely a component datasheet.

Small 29.4 KB PDF bearing only the part number 2sj146. The 2SJ prefix in Japanese JIS naming designates a P-channel field-effect transistor, so treat this as a compact…

A 420 KB PDF covering the 2SJ402, whose 2SJ prefix under Japanese JIS designation marks a P-channel field-effect transistor.

A 320 KB PDF for the 2SJ380, catalogued under schematics but by its number a transistor datasheet. In JIS designation, 2SJ parts are P-channel field-effect transistors.

PDF file of about 148 KB describing the 2SJ315, listed in the schematic section. No board or brand is mentioned, only the part number.

The 2SJ312 is documented in this 362 KB PDF, catalogued as a schematic. Beyond the part number the name says nothing about the equipment involved.

Datasheet-type PDF of 47.9 KB for the 2SD894, placed under schematics. The name holds only the part number, which follows JIS conventions where 2SD indicates an NPN…

The 2SC4504 transistor is covered by this 83.2 KB PDF data sheet. Its 2SC prefix follows Japanese JIS numbering for NPN bipolar devices; the name gives no manufacturer…

Part code 2SC4440 is all the 97.3 KB PDF name reveals, and the catalogue places it under schematics.

At 466 KB, this PDF for the 2SC4325 sits under schematics, yet the name is a bare transistor part number, so expect a component datasheet.

Listed under schematics, this 133 KB PDF named 2SC5108FT appears to be the datasheet for an FT-suffixed variant of the 2SC5108 transistor.

PDF reference for the 2SC4248 transistor, 300 KB in size. Beyond the part number the file name gives no information about manufacturer, package or revision.

Compact 29.9 KB PDF for the 2SC5775 transistor, filed under schematics despite the name being a bare part number.

PDF of 49.9 KB titled 2SC5568, indexed among schematics. The file name offers nothing besides the part number; the 2SC prefix follows JIS/JEITA naming for NPN…

PDF for the 2SC5548A, an A-suffix variant of the 2SC5548 NPN transistor, 231 KB and indexed as a schematic.

Sized at 316 KB, this PDF covers the 2SC5422, a part number in the Japanese JIS series used for NPN bipolar transistors.
