TOSHIBA Transistor Silicon NPN Epitaxial Type (PCT process)
2SC2240
2SC2240
Low Noise Audio Amplifier Applications
The 2SC2240 is a transistor for low frequency and low noise
applications. This device is designed to lower noise figure in the region of
low signal source impedance, and to lower the pulse noise. This is
recommended for the first stages of Equalizer amplifiers.
· Low noise : NF = 4dB (typ.) R
f = 1 kHz
: NF = 0.5dB (typ.) R
f = 1 kHz
· Low pulse noise: Low 1/f noise
· High DC current gain: h
· High breakdown voltage: V
