Circuit schematic in PDF for Sony board MBX-202, identified by the M790 code, about 788 KB.

PDF of about 25.4 KB for the 3SK303 semiconductor, filed in the schematic category. The file name holds only the part number.

Component sheet for the 3SK268 supplied as a 32.8 KB PDF and placed in the schematic category. Beyond the part number, the name gives no further detail.

This 91.1 KB PDF covers the 2SD1887 transistor; it sits in the schematic category but the file name matches a JIS component designation, pointing to a datasheet.

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…

Datasheet-type PDF of 419 KB named after the 2SK2314. The 2SK prefix in the Japanese JIS designation identifies an N-channel field-effect transistor, so this…

The 2SK1442 is the sole detail in the name of this 107 KB PDF, which is categorised as a schematic.

Documentation for the base 2SC5265 part, a 112 KB PDF in the schematic category. Under JIS designations 2SC stands for an NPN bipolar transistor; a separate LS-suffixed…

At 153 KB, this PDF named 2SC4399 is presumably the datasheet for that NPN bipolar transistor, even though the index lists it as a schematic.

Component documentation for the 2SC4269 in PDF form, 108 KB in size, listed in the schematic category. Nothing beyond the part number appears in the name.

PDF part sheet for the 2SC5577, 40.7 KB, catalogued with schematics. The name gives only the part number and says nothing about the maker or revision.

A 305 KB PDF for the 2SC4246 transistor. The name states nothing apart from the part number, so the manufacturer and revision have to be read inside the document.

The 2SC3996 is covered by this 91.9 KB PDF, sorted under schematics although a name consisting only of a part code usually means a datasheet.

The 2SC3987 document is an 83.4 KB PDF whose name contains only the part number, so expect a transistor datasheet rather than a device schematic, even though it is…

For the 2SC3597 transistor, a 119 KB PDF filed as a schematic but containing component data.

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…

Datasheet for the 2SC3495 in a 91.6 KB PDF, indexed in the schematic category. By Japanese JIS naming, the 2SC prefix identifies an NPN bipolar transistor designed for…

Only the part number 2SC3361 appears in the name of this 129 KB PDF, so no equipment or board can be identified from it.

The 152 KB PDF is labelled 2SC5355, a Japanese JIS transistor designation in which 2SC identifies an NPN device of the high-frequency category.

Transistor datasheet in PDF form for the 2SA720A, 42.4 KB, with an _E suffix whose meaning the name does not state.

Data sheet style PDF of 189 KB named 2n1792, listed under schematics. The lowercase name follows the JEDEC 2N pattern for discrete semiconductor devices, and no…

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.

Catalogued as a schematic, this 56.9 KB PDF is labelled 1SV237. The trailing underscore in the name appears to be a naming artefact, not part of the code.

Listed among schematics, this 78.7 KB PDF covers the 1SS399, a number that follows the Japanese 1SS small-signal diode designation.

A 144 KB PDF filed under schematics for the 220CNQ030, a designation that matches the CNQ family of high-current Schottky rectifier modules.

A 111 KB PDF named 555 and grouped with schematics, with no brand or board stated. The number matches the widely used 555 timer designation, but the document should be…

PDF of 337 KB catalogued as a schematic under the name 78F0034A. No board number, brand or revision is stated; the code resembles a microcontroller part number rather…

Part-code document named 30CLJQ100, a 51.5 KB PDF that the index lists as a schematic. The name gives no laptop model, board number or revision, only the component…

A schematic-category PDF of 223 KB named 20CTQ, without any device model, board number or revision in the name.

Board layout for BM5012 revision 1.3 supplied as a 178 KB PDF rather than a native boardview format, according to the name. No brand or model is stated.
