Second volume, 30.0 MB, of a split RAR archive with a numeric name that gives no clue about the device, board or file type inside.

Raw 8.00 MB firmware dump named x200 with the extra tokens ma r, whose meaning is not clear; no brand or board number is stated, so the source device must be confirmed.

ZIP archive of BIOS files labelled a100-105, 875 KB. The name suggests versions or models in an A100 to A105 range, but gives no brand or device, so its target needs…

Small RAR archive of 48.8 KB tied to the AlphaBox X6 receiver. The name gives no version, date or content type, and the low size points to settings, a channel list, a…

Image read from a Winbond W25Q256FV flash in an 8x6 mm WSON-8 package, a 256 Mbit, 3.3 V chip, producing a 32 MB file with a programmer timestamp.

Timestamped 16 MB flash readout taken from a Winbond W25R128JV SPI chip, as the name indicates; the device it came from is not stated.

Firmware dump identified only by the Macronix MX25L6473 flash chip, a 64 Mbit (8 MB) SPI part; the name gives no device or board number.

Archived dump read from a GigaDevice GD25Q128B flash chip in a WSON8 package, which holds 128 Mbit (16 MB).

BIOS archive for the HP EliteBook x360 1020 G2 on mainboard 6050A2895901-MB-A01, compressed as a 7.96 MB RAR.

Part document for the 2SC4517, a 27.9 KB PDF listed as a schematic; the name holds only the part number.

Datasheet for the 2SC4517, a JIS-numbered NPN bipolar transistor, delivered as a 26.9 KB PDF.

Reference for the FGH40N60SFD IGBT, with the name stating 40 A and 600 V, supplied as a 463 KB PDF.

PDF covering the BUW84 and BUW85 transistors in a single 101 KB document, filed as a schematic.

Named 3LN02C, this 41.8 KB PDF is filed among schematics but its name is a component-type code with a C suffix and gives no device or board details.

Another copy of documentation for the 2SD1458 NPN transistor, stored as a 48.8 KB PDF under a lowercase file name.

Stored under a lowercase name, this 52.3 KB PDF covers the 2sd2318 transistor. In the Japanese JIS scheme the 2SD series contains NPN devices for low-frequency duty, so…

Component document for the 2SK2611, a part number in the Japanese JIS scheme where the 2SK prefix marks an N-channel field-effect transistor.

The smallest sheet of its group at 24.4 KB, this PDF concerns the 2sk2573, an N-channel field-effect transistor by the JIS 2SK prefix.

Compact 33.0 KB PDF on the 2SK1834 transistor. The 2SK prefix belongs to the Japanese JIS designation system and means an N-channel field-effect device, so the content…

Datasheet-style PDF for the 2SK669, a part number in the JIS 2SK series used for N-channel field-effect transistors, listed in the index as a schematic.

At just 31.4 KB, the PDF named 2SJ499 is probably a short datasheet or summary sheet, even though it is filed as a schematic.

The 2SJ419 is covered by this 100 KB PDF, filed under schematics though the part number points to a discrete transistor datasheet.

At 294 KB, this PDF is larger than its neighbours but still identified only by 2SJ167, a Japanese JIS number for a P-channel field-effect transistor.

Samsung SM-A127F repair archive in RAR format, about 2.29 MB, named only by the model code with no hint of its exact contents.

Copy-numbered RAR archive for the OPPO R7s, 1.29 MB, matching the size of the other R7s package and therefore probably a duplicate.

PDF document of 41.7 KB for the 2SC4737, filed in the schematic category but named after a part rather than a board.

Filed under schematics, this 98 KB PDF is named after the part number 2SC4671, which follows the Japanese JIS designation for an NPN bipolar transistor.

The 2SC4163 part number is all this 98.9 KB PDF name reveals, so although labelled a schematic it is best read as a transistor datasheet.

Named only 2SC4161, this 98.6 KB PDF is categorised as a schematic yet, judging by the part number, documents an NPN bipolar transistor under the JIS designation scheme.

Named in lowercase for the 2sc4132, this 63.0 KB PDF is classed as a schematic but is better understood as the datasheet for an NPN bipolar transistor, which is what the…

Stored under schematics, this 93.8 KB PDF is named for the 2SC4123 and is expected to hold the transistor's datasheet rather than a circuit drawing.

The largest of this group at 334 KB, this PDF is named only 2SC4117 and, while labelled a schematic, should be the datasheet for that NPN bipolar transistor under…

Small 95.8 KB PDF for the 2SC4109, indexed with the schematics. The file name gives nothing beyond the part number; the 2SC prefix identifies an NPN bipolar transistor…

Small PDF of 25.0 KB dedicated to the 2SC4064, catalogued as a schematic. Going by JIS semiconductor numbering, 2SC marks an NPN bipolar transistor; the name gives no…
