IFNU421 Datasheet | InterFET

Features - Inter FET N0001H Geometry - Low Leakage: 0.25 p A Typical - Low Input Capacitance: 2.0 p F Typical - High Input Impedance - Replacement for U421, U422, U423 - Ro HS pliant - SMT, TH, and Bare Die Package options. Applications - Low Leakage Input Buffer - High Frequency Amplifier/Buffer - Ultrahigh Impedance Pre-Amplifier - Impedance Converters Description The -40V Inter FET IFNU421, IFNU422, and IFNU423 JFET’s are targeted for ultra high input impedance applications for differential amplification and impedance matching. Gate leakages are less than 1p A at room temperatures. The TO-78 package is hermetically sealed and suitable for military applications. Custom specifications, matching, and packaging options are available.
