Spanish-language electronics series El mundo de la electronica, issue 18, around 1010 KB as a PDF.

Only 28.2 KB, this PDF named 2sk123 is catalogued as a schematic, but the name is a JIS transistor number, so a short datasheet is the likely content.

A compact 122 KB PDF named after the 2SK2260, filed in the schematic category but most likely the datasheet for that device.

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

The 2SC4861 datasheet appears to be what this 117 KB PDF contains, although it is filed in the schematic category. Only the part number is stated.

A 147 KB PDF whose name is just 2SC2881, catalogued as a schematic. By JIS numbering this is an NPN bipolar transistor, and the file is most likely its datasheet rather…

The 2SB1674 named here is, under JIS conventions, a PNP bipolar transistor; this 52.6 KB PDF, despite its schematic category, is therefore most likely the datasheet.

The 2SB767 is covered by this 42.9 KB PDF, whose name adds only an _E suffix that cannot be decoded from the name alone.

The 1T404 code is all the name reveals about this 52.4 KB PDF, which is listed as a schematic. No device, maker or board number is stated.

At 82.2 KB, the 1SV228 PDF is the largest of this group and is indexed as a schematic. The underscore after the code seems to be just part of the file naming.

Only 34.2 KB, this PDF is named 1N957, a JEDEC 1N diode designation, and is better described as a component datasheet than a schematic.

Labelled 80EPS08, this 80.7 KB PDF is classed as a schematic but carries a semiconductor part code in International Rectifier style, so it most likely contains a…

Named 80EPF02 and 145 KB in size, this PDF is catalogued as a schematic but the code is a rectifier diode part number in International Rectifier format, so the content…

PDF document of 41.0 KB for the 2SD2185 transistor, with an _E suffix in the file name that is not decoded here.

Covering the 2SK2459N, this 138 KB PDF sits in the schematic section but by its name is a transistor datasheet; 2SK is the Japanese JIS prefix for N-channel field-effect…

A 95.0 KB PDF named after the 2SK1908, listed in the schematic section of the index. Since 2SK is the Japanese registration prefix for N-channel FETs, treat it as the…

A 51.7 KB PDF for the 2SC4208, with an _E suffix in the name whose meaning is not stated; it could mark an edition or language version, but that is unconfirmed.

A small PDF filed as a schematic, though the name is simply the part number 2SC3468, which follows the Japanese JIS semiconductor scheme where the 2SC prefix marks an…

A 186 KB PDF identified by the part number 2SC2873 and classed as a schematic. Under the JIS standard the 2SC prefix means an NPN bipolar transistor, so this is most…

A 53.4 KB PDF for 2N5551, carrying a Sam tag in brackets that likely names the publishing manufacturer, though the abbreviation is not spelled out.

Labelled 100mt160p, this 90.2 KB PDF is filed as a schematic though its title resembles a component part number, not a motherboard designation.

SM7250 processor schematic in PDF format, 1.37 MB, with no handset model or revision named.

The 2SK2035 transistor is the subject of this 295 KB PDF, most likely the manufacturer datasheet given that 2SK is the JIS prefix for N-channel FETs.

For the 2SK614, a part number from the JIS family of N-channel field-effect transistors, this 32.7 KB PDF is catalogued as a schematic but is most plausibly a short…

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

Listed under schematics, this 188 KB PDF is named for the JEDEC part 2N5550 with an RE suffix whose meaning is unclear. No laptop, board code or revision is given.

Portuguese introductory study material on digital electronics, the first part of a course series judging by the numbering in the name.

Although filed as a schematic, this 37.9 KB PDF is named after 2SD2460 with an extra E tag the name does not explain.

The 2SJ225 is the only information this 91.8 KB PDF name provides; the 2SJ prefix in Japanese semiconductor numbering identifies a P-channel field-effect transistor.

Part number 1T409 is the only information in the name of this 49.5 KB PDF, which is catalogued as a schematic.

The 1SS398 is the subject of this 78.2 KB PDF, which is catalogued as a schematic but is likely a single-part datasheet.

El mundo de la electronica issue 20, a Spanish educational publication in PDF format at 1.71 MB, one of the larger files in the series.
