HCF4050 reference document in PDF format, 175 KB, covering the 4050 hex non-inverting buffer in its HCF-prefixed version.

For the 2SK3411 transistor, this 32.0 KB PDF provides the component reference, even though the index files it as a schematic.

Datasheet-style PDF for the 2SK3018, indexed here under schematics, though the 2SK prefix marks a Japanese JIS-registered N-channel field-effect transistor rather than a…

Part number 2SK2231 is the only information carried by this 420 KB PDF, which the index places among schematics but which most likely documents a single transistor.

Compact 31.6 KB PDF dedicated to the 2SK2032. Because 2SK identifies an N-channel field-effect transistor in the Japanese numbering scheme, this is effectively a…

The 2SK1920 is the only detail in this file name, and the 93.1 KB PDF is indexed as a schematic.

Part 2SK1890, documented in a 96.7 KB PDF placed in the schematic category. Japanese JIS numbering reserves 2SK for N-channel FETs, so this is a component datasheet…

For the 2SK1470, a Japanese-coded N-channel field-effect transistor, this 97.9 KB PDF serves as component reference material even though it sits in the schematic…

This 93.0 KB PDF carries the part number 2SJ258 and nothing else. The 2SJ prefix, under Japanese JIS numbering, indicates a P-channel field-effect transistor, so expect…

Named only 2SJ232, this 88.9 KB PDF relates to a P-channel field-effect transistor, as indicated by the JIS 2SJ prefix.

The 123 KB PDF bears the part number 2SC4644 and nothing else. That makes it a reference for a single NPN transistor rather than a full circuit diagram, despite the…

Filed under schematics, this 244 KB PDF is named after the part number 2SC4479, which follows the Japanese JIS scheme where the 2SC prefix marks an NPN bipolar…

Reference PDF for the 2SC4224, at 97.3 KB, catalogued as a schematic although the name is just a semiconductor part number.

Short 30.1 KB PDF for the 2SC5778 transistor, placed in the schematic category. Japanese JIS codes beginning with 2SC denote NPN bipolar devices, so the contents are…

Filed under schematics, this 209 KB PDF is named after the part number 2SC3405, which follows the Japanese JIS scheme where the 2SC prefix marks an NPN bipolar…

Brief 41.4 KB PDF for the 2SC3117, which JIS numbering identifies as an NPN bipolar transistor.

A 145 KB PDF labelled only 2SC2839, catalogued under schematics. The JIS 2SC prefix indicates an NPN bipolar transistor, so this is most likely a datasheet rather than a…

Part reference for the 2SC1518 in a 51.5 KB PDF carrying an _E suffix, filed under schematics.

Datasheet PDF for the 2N4031 part number, 52.3 KB in size, placed in the schematic category of the index.

Named simply 1N821, this 34.4 KB PDF follows JEDEC 1N diode numbering and is most likely a single-part datasheet, not a circuit diagram, even though it sits in the…

PDF document, 134 KB, for the 23c040 part, catalogued among schematics. The 23C numbering is typical of mask ROMs, with 040 usually meaning 4 Mbit capacity, though the…

Schematic PDF, 1.16 MB, named Tin Yat 80A. Tin Yat appears to be a project code name, with 80A as a variant or revision marker, though the name does not state a brand.

Schematic for a model named SL410K, supplied as a 1.58 MB PDF; the name states no brand, board number or revision, so read the title block to confirm the platform.

First chapter of a Spanish course on cellular telephony, a 1.95 MB PDF filed under schematics but evidently a training lesson. It names no device or board number.

Panasonic service schematic for the TH-L32C22D LCD television, chassis KM06V, reference PAVCI1006012CE.

Schematic for the ASUS X545FB laptop motherboard, delivered as a PDF inside an 8.7 MB RAR archive.

Schematic PDF for Quanta board DA0BLKMB6E0, project BLK as the OBLK suffix suggests. The name gives no laptop brand or model, only the Quanta board code, so identify the…

Schematic PDF of 260 KB with the code RSAG7.820.7748 in its name, a format typical of Hisense TV main or power board part numbers, preceded by the abbreviation FA.

Schematic for the ASUS ROG GL502VT at board revision 2.0, supplied as a PDF inside a RAR archive.

PDF schematic for the ASUS FX505DD laptop mainboard, revision 2.0, stored in a 3.58 MB RAR. The name gives no further variant details.

Schematic in PDF format, 1.45 MB, named UX50, which corresponds to a notebook model designation; no brand, board number or revision is stated in the name.

IBM ThinkPad T61 schematic in PDF form, around 2.21 MB. The name states the model only, with no board number, revision or graphics variant, and T61 boards existed with…

PDF circuit diagram for the Z62H board, about 809 KB in size. The file name states only the board code; brand, laptop model and revision are not given.

Shuttle schematic in PDF for board 71R-H14BT4-TL30, with H14BT01-4L also listed in the name, likely the project name with 4L hinting at a four-layer PCB.

Notebook schematic for the Quanta Y0K project, revision 1A, with 192016 in the name likely being a date code. The 1.25 MB PDF gives no brand or chipset information.

Schematic of the Arroyo3 board in PVT stage, number 6050A2516401, revision A01, as a 1.01 MB PDF. PVT refers to the production validation build.

Schematic for the Samsung NP-R710 laptop, an unlocked PDF copy, which means the file should allow printing, copying and text search without password restrictions.

Schematic for the Fujitsu Siemens Amilo M1451G notebook, with M50EA0 in the name, likely the design code of its mainboard.

PDF schematic for the Dell Inspiron 15-3542, built by Wistron under the Cedar project name on board 13269-1, Dell part FX3MC. The (2) suffix only marks a duplicate copy.
