Description
LSJ109 N-CHANNEL JFET Linear Systems replaces discontinued Siliconix J109 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 SOT-23 package is well suited for cost sensitive applications and mass production. (See Packaging Information).
