Micross U423

The U423 is a high input impedance Monolithic Dual N-Channel JFET The U423 monolithic dual n-channel JFET is designed to provide very high input impedance for differential amplification and impedance matching. The U423 is a direct replacement for discontinued Siliconix U423. The hermetically sealed TO-71 & TO-78 packages are well suited for military applications.
