Troubleshooting guide in PDF for the Samsung I9060 handset, with Tshoo being Samsung's usual short form for troubleshooting.

Datasheet for the EMB04N03H, a MOSFET from Excelliance MOS, provided as a 224 KB PDF. The part number suggests an N-channel device rated around 30 V, as used in notebook…

Filed as a schematic, this 464 KB PDF carries just the name 2SC4322 and should be read as a transistor datasheet.

The 2SC5540 transistor is covered by this 30.9 KB PDF, catalogued as a schematic. By JIS convention the 2SC prefix signifies an NPN bipolar device, so the document is…

A 41.3 KB PDF named 2SC5018 with an additional _E suffix that the name does not explain.

Small 41.6 KB PDF for the 2SC5388, a JIS-numbered NPN bipolar transistor; the file name states only the part number, so package, maker and application are not given.

Short 108 KB PDF datasheet for the 2SC3601, placed in the schematic section of the index.

Reference sheet for the 2N4264, saved as a 264 KB PDF and carrying an RE tag in the file name that is not explained further.

The name identifies only the part 1SS377, so this 69.8 KB PDF is best treated as a diode data sheet even though it is indexed as a schematic.
