Description
U441 MONOLITHIC DUAL N-CHANNEL JFET
Linear Systems replaces discontinued Siliconix U441
The U441 is a tightly matched Monolithic Dual N-Channel JFET
The U441 are monolithic dual JFETs mounted in a single TO-71 package. The monolithic dual chip design reduces parasitics and gives better performance at very high frequencies while ensuring extremely tight matching. These devices are an excellent choice for use as wideband differential amplifiers in demanding test and measurement applications. The U441 is a direct replacement for discontinued Siliconix U441. The hermetically sealed TO-71 is well suited for military applications. (See Packaging Information). U441 Applications: Wideband Differential Amps High-Speed,Temp-Compensated SingleEnded Input Amps High-Speed Comparators Impedance Converters and vibrations detectors.
