Short datasheet, around 78.7 KB, for the HC-SR04 ultrasonic distance sensor module widely used in hobby and educational electronics.

Small 89.9 KB PDF datasheet labelled only with document number 2669, so the title reveals neither the component nor its maker.

BIOS image named only as new bios, with no model, brand or board reference, stored as a 32 MB binary.

Schematic in PDF for laptop motherboard 18803-1, a number following the Wistron ODM pattern; the name gives no laptop model.

Datasheet for the BC557 small-signal PNP transistor, a 45.8 KB PDF that matches the size of the other BC557 files in this collection.

Datasheet-style PDF for the 2SD2611, stored in the schematic category at 47.3 KB. The name gives only the part number, so revision and manufacturer are not stated.

Document for the 2SD1624, a PDF of 144 KB stored in the schematic section; with only a part number in the name it should be treated as a datasheet.

Small PDF of 27.3 KB for the 3LN01N, catalogued as a schematic though the name reads as a discrete transistor part number, so it is most likely a datasheet.

Filed under schematics, this 74.1 KB PDF is named after the 2SD1953, which in Japanese JIS numbering is an NPN transistor for low-frequency applications.

Datasheet-style PDF of 83.8 KB named for the 2SD1940, an NPN transistor under Japanese JIS numbering, in which 2SD stands for NPN low-frequency types.

A 133 KB PDF for the 2SD1935, a transistor in the Japanese 2SD family, which the JIS standard reserves for NPN low-frequency devices.

At only 34.4 KB, this PDF is a short reference for the 2SD1913 transistor. Under Japanese JIS part numbering the 2SD prefix identifies an NPN device for low-frequency…

Catalogued as a schematic, this 156 KB PDF is named after the 2SD1906, a Japanese JIS part number, so it is most likely the component datasheet for that transistor…

A small 40.3 KB PDF for the 2SK2867, filed as a schematic; the modest size suggests a short datasheet or summary page. The name contains nothing but the part number.

Component datasheet for the 2SD882S transistor as published by UTC (Unisonic Technologies), filed here under schematics although it is a part specification rather than a…

Filed as a schematic, this 120 KB PDF is named only after the part number 2SC4402, so it is most likely the manufacturer datasheet for that transistor rather than a…

A 98.4 KB PDF titled with the part number 2SC4162, filed under schematics but in practice expected to be the datasheet for that transistor.

A brief 38.9 KB PDF named after the 2SC4119, filed as a schematic but most likely a short datasheet for that transistor.

PDF reference sheet for the 2SC3184, filed in the index as a schematic but named after a single part number in the Japanese JIS scheme.

PDF document for the 2SA1635, filed under schematics but in fact a component sheet for a discrete transistor; the _1-2 suffix in the name likely marks a part or revision…
