Pinout of 2SC1890-F

The 2SC1890-F is manufactured in a plastic TO-92 case. When looking at the flat side with the leads pointed downward, the three leads emerging from the transistor are, from left to right, the emitter, collector, and base leads.
Here is an image showing the pin diagram of this transistor.

Classification of hFE

The 2SC1890-F transistor can have a current gain of 600 to 1200. The gain of the 2SC1890 will be in the range from 250 to 1200, for the 2SC1890-D it will be in the range from 250 to 500, for the 2SC1890-E it will be in the range from 400 to 800.

Marking

Sometimes the "2S" prefix is not marked on the package - the 2SC1890-F might only be marked "C1890-F".
