J108
J108 is N-CHANNEL JFET manufactured by Micross.
J108 N-CHANNEL JFET
Linear Systems replaces discontinued Siliconix J108
This n-channel JFET is optimised for low noise high performance switching. The part is particularly suitable for use in low noise audio amplifiers. The TO-92 package is well suited for cost sensitive applications and mass production. (See Packaging Information). Features
