MSI firmware bundle for boards MS-16K2 and MS-16K21, containing a BIOS image, EC firmware and keyboard EC (KBEC) files, with 8 MB and 1 MB sizes listed in the name.

Firmware set for the Lenovo Legion Y545 on LCFC board NM-C221 Rev 2.0, holding the system BIOS at version BHCN32WW plus the embedded controller firmware for the ITE EC…

PDF of 176 KB for the 2SD2384, an NPN bipolar transistor going by its JIS 2SD prefix, filed as a schematic in this index.

PDF of 173 KB for the 2SC4707, sorted into the schematic category. Because 2SC is the JIS/JEITA designation for NPN bipolar transistors, expect a component datasheet…

Reference PDF, 170 KB, for the 2SD1525 transistor, listed under schematics. Japanese JIS designation 2SD identifies an NPN bipolar device meant for low-frequency work.

Transistor datasheet for the 2SA1822 in PDF, 173 KB, filed under schematics in this index. JIS numbering uses the 2SA prefix for PNP bipolar transistors.

PDF datasheet for the 2SD2406 transistor, a larger 176 KB file in the schematic category.

PDF component sheet, 173 KB, named for the 2SK2969. Under the Japanese JIS numbering a 2SK part is an N-channel FET, which makes this a transistor datasheet despite its…

Reference PDF, 171 KB, for the 2N5877 discrete semiconductor, labelled a schematic but most likely a manufacturer datasheet. The RE suffix in the name is not defined.

Covering the 2SC5198, this 171 KB PDF sits in the schematic category but carries only a transistor part number, so treat it as a datasheet.

A 171 KB PDF for the 2SC5196 transistor, grouped under schematics although the name points to a datasheet.

The 2SC3671 transistor is documented in this 178 KB PDF, which the catalogue lists as a schematic.

For the 2SA1392, this 174 KB PDF provides the part reference, categorised as a schematic although the name points to a single transistor.

Component document for 2SA1987, a 173 KB PDF. Following the Japanese JIS convention, the 2SA prefix designates a PNP bipolar transistor, so the file is expected to be a…

Datasheet in PDF form, 175 KB, for the 74AHC1G00, a single two-input NAND gate from the 74AHC logic family in a small package.

Stored under schematics, this 171 KB PDF is named 2SD1407A and is most probably the datasheet for that transistor variant, the A suffix distinguishing it from the base…

Reference PDF of 178 KB for the 2SC4682. Although catalogued as a schematic, the part number uses the Japanese JIS scheme where 2SC identifies an NPN bipolar transistor…

The 2SA1483 is covered by this 178 KB PDF, catalogued under schematics though the name suggests a component data sheet.

Sharing its 173 KB size with a neighbouring entry, this PDF is named 2SA1986, the JIS number of a PNP bipolar transistor.

Document numbered UM10155, a 179 KB PDF. The UM prefix is used by NXP for user manuals, but the name does not reveal which product it describes, so open it to identify…

Samsung BN44-00520C power board schematic, a compact 176 KB PDF, revision C per the name.

Datasheet for the LTC4412HV from Linear Technology, a low-loss PowerPath controller that drives an external P-channel MOSFET as an ideal diode.

Summary datasheet for the ATmega406 AVR microcontroller, a 179 KB PDF. The ATmega406 is aimed at smart battery management, so this part often turns up inside laptop and…

PDF of about 179 KB for the 2SD2531, filed as a schematic but probably the component datasheet.

A 173 KB PDF covering the 2SD2386, an NPN bipolar transistor by its JIS 2SD designation, listed in the schematic section.
