Additional Details

The 2SK369-GR(F) typically features a gate-source breakdown voltage (VGSS) of around 30V and a drain current (IDSS) that varies depending on the specific grade (GR in this case). The low noise figure, typically in the range of a few dB, makes it an excellent choice for amplifying weak signals without introducing significant noise. It is commonly used in the front-end stages of audio amplifiers and RF receivers to maximize signal-to-noise ratio. The package is typically a small through-hole or surface-mount type, facilitating easy integration into circuit designs. This is a depletion mode device.
