Short 27.5 KB PDF for the 2SC3751 NPN transistor, the smallest file in this group, so it is probably a brief specification or summary sheet.

Part documentation for the 2SA1415 transistor, delivered as a 116 KB PDF and indexed as a schematic.

Datasheet PDF, 292 KB, for the 2SK1829 transistor. Under JIS naming, 2SK marks an N-channel FET; the file name gives only the part number, with no maker or package…

PDF of 61.5 KB for the 2SA1870, with a 1-2 tag in the name. That tag may indicate one part of a split document or a revision, but the name does not say which.

File name 2SC3786 offers nothing beyond a transistor type number, and the 81.5 KB PDF is placed in the schematic category.

Stored as a 101 KB PDF, this entry describes the 2SC3746, a JIS-numbered NPN bipolar transistor, and is filed under schematics in the catalogue.

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…

The 2SC4030 transistor is documented in this 119 KB PDF, which is listed in the schematic section.

By Japanese JIS numbering the 2SB643 is a PNP bipolar transistor, so this 44.2 KB PDF labelled as a schematic should be its datasheet, with _E probably marking an…

This 145 KB PDF carries only the part number 2SC2884 in its name and is filed as a schematic.

A compact 36.0 KB PDF for the 2SD1949 transistor. The 2SD prefix in the JIS system designates an NPN device for low-frequency circuits, so the content is expected to be…

Very small at 26.8 KB, this PDF is identified only as 2SC4826, a JIS transistor code in which 2SC marks an NPN type.

A 64.4 KB PDF for the 2SA1906, with a 1-2 suffix in the name that may indicate the first of two pages or parts; the exact meaning is not stated.

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.

Schematic in PDF form for the Biostar IG31K-M7S desktop motherboard, version 6.2S, compressed into a 975 KB RAR archive.

Schematic diagrams for the original Xiaomi Mi 2 phone, compressed into a 1.87 MB ZIP. The name lists no board number or revision and does not mention the later Mi 2S, so…

Schematic set for the Xiaomi Mi 2S smartphone in a ZIP archive of roughly 1.22 MB. The name gives only the model, with no board number or revision, so compare the…

Circuit diagrams for the Xiaomi Mi 2S phone, delivered in a 1.22 MB ZIP archive. No mainboard number or revision appears in the name, so confirm the drawings match your…
