J212
N-CHANNEL JFET
Linear Systems replaces discontinued Siliconix J212
The J212 is a n-channel JFET General Purpose
amplifier with low noise and low leakage.
The SOT-23 package is well suited for cost sensitive
applications and mass production.
(See Packaging Information).
J212 Benefits:
 High gain
 Low Leakage
 Low Noise
J212 Applications:
 General Purpose Amplifiers
 UHV / VHF Amplifiers
 Mixers
 Oscillators
