J201_TO-92 Datasheet, PDF (1/1 Pages) Micross Components – a high gain N-Channel JFET
J201
N-CHANNEL JFET
Linear Systems replaces discontinued Siliconix J201
The J201 is a high gain N-Channel JFET
This n-channel JFET is optimised for high gain. The
part is particularly suitable for use in low power or high
impedance amplifiers. The TO-92 package is well
suited for cost sensitive applications and mass
production.
(See Packaging Information).
J201 Benefits:
ƒ High Input Impedance
ƒ Low Cutoff Voltage
ƒ Low Noise
J201 Applications:
ƒ Battery powered amplifiers
ƒ Audio Pre-Amplifiers
ƒ Infra-Red Detector Amplifiers
