Repair guide for the P553UJ notebook, abbreviated RG in the name, in a 726 KB PDF. These guides normally combine board photographs, component locations, typical voltage…

Component documentation for 5HP02M, delivered as a 40.7 KB PDF. Despite the schematic label, the name is a bare part number with no board or brand information, so treat…

Component sheet for the 3LN01M, a 41.2 KB PDF filed in the schematic category. The name is only a part code; sibling files 3LN01N and 3LN01C share the base number, so…

A 41.8 KB PDF named for the 2SD2457 with an E tag, filed as a schematic. By the JIS scheme, 2SD marks an NPN bipolar transistor, so expect a component reference rather…

Datasheet-style PDF of 118 KB for the 2SD1898, recorded in the index as a schematic but named after a single component.

Reference sheet for the 2SK2739 in PDF format, 146 KB, indexed in the schematic section.

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

A compact 27.8 KB PDF named after 2SJ164, a JIS designation identifying a P-channel FET.

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.

Filed as a schematic, this 59.7 KB PDF is titled 2SC5128 and presumably holds the datasheet of that NPN bipolar transistor.

At 108 KB, this PDF is labelled with the transistor type 2SC4221 and nothing else, so no board, model or revision is identified.

Part 2SC3991 is the only information carried by this 113 KB PDF, which the index lists as a schematic although the name points to a discrete component datasheet.

Covering the 2SC3811, this 45.7 KB PDF has an _E suffix in its name, which is not explained and may denote an edition or English version.

Specifications for the 2SC3656 in PDF form, 90.4 KB. Parts beginning with 2SC in the JIS system are NPN bipolar transistors.

Component reference for the 2SC3392, provided as a 155 KB PDF in the schematic category.

The 2SC3144 NPN transistor is documented in this 117 KB PDF, filed as a schematic though it is most likely a component data sheet.

This 183 KB PDF takes its name from the 2SC2840 and is indexed as a schematic. In Japanese JIS designations, 2SC means an NPN bipolar transistor, so the document is…

PDF of 42.0 KB covering the 2SB1392 transistor. The name provides only the part number; manufacturer, package and revision are not given.

The 2SA1564 is covered by this 90.3 KB PDF, which is labelled as a schematic but named after a discrete component.

Part document for the 2SA1511, an 88.3 KB PDF filed in the schematic category. Its name follows the Japanese JIS designation in which 2SA denotes a PNP bipolar…

Named after part 2N5485, this 755 KB PDF has no board, device or revision details. It shares its size with the 2N5484 and 2N5486 entries, so it is likely the same family…

PDF reference sheet for the 2N5320 transistor, 45.0 KB, sitting alongside the 2N5322 document in the index. No vendor or revision is named.

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.

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.

Catalogued as a schematic, this 74.6 KB PDF is named after the 1SV269 part number, with a trailing underscore that carries no extra information.

PDF reference for the 1SS404 part, filed under schematics, though the 1SS numbering points to a Japanese small-signal diode and the file is probably its datasheet.
