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.

PDF schematic of 1.53 MB labelled y16e, with dual and si tokens, a 0527 date-like code and a bom 15 reference in the name; no brand or board number is stated, so the…

Second of four RAR volumes in a collection labelled, in Russian, schematics and boardviews, sized 1.76 GB.

Schematic in PDF form marked 1201T revision 2, with the unlocked tag meaning the document's protection has been removed so it can be printed or searched freely.

Schematic PDF named simply AP2, 274 KB in size, with no device, brand or board number in the name.

First file of the LA46 drawings series in PDF, discrete-graphics (DIS) version, only 25.2 KB in size.

Disassembly guide for the Samsung SM-E500H, a 598 KB PDF even though it is listed under schematics.

Service schematic in PDF for the Samsung Galaxy SM-J530F smartphone, a 4.73 MB document covering the main logic board circuitry.

Apple iPad mini 1 schematic as a 2.19 MB PDF document, covering the first-generation mini's logic board circuitry.

Small 113 KB PDF for an Acer device, labelled with the Compal LS-5673P number, with the label repeated in the name.

Schematic for a Samsung Galaxy Core Plus, labelled gt 18580, a 5.99 MB PDF. The model code likely corresponds to the GT-I8580 Galaxy Core Advance or a similar unit, but…

PDF of 73.0 KB labelled as LA46 drawings, DIS version, with a truncated title that names no device, board number or revision.

Small schematic covering the touchpad board for the Sony MS70 project, associated with the MBX-160 mainboard, at revision 0.20.

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

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.

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.
