U444 - N-Channel JFET Pairs

Download the U444 datasheet PDF. This datasheet also covers the U443 variant, as both devices belong to the same n-channel jfet pairs family and are provided as variant models within a single manufacturer datasheet.

Key Features

  • high speed amplification (slew rate), high gain (typically> 6 mS), and low gate leakage (typically < 1 pA). This performance makes these devices perfect for use as wideband differential amplifiers in demanding test and measurement.

U443 SERIES N-Channel JFET Pairs The U443 Series are matched pairs of JFETs mounted in a single TO-78 package. This two chip design reduces parasitic performance at high frequency while ensuring extremely tight matching. The U443 features high speed amplification (slew rate), high gain (typically> 6 mS), and low gate leakage (typically < 1 pA). This performance makes these devices perfect for use as wideband differential amplifiers in demanding test and measurement applications. Finally, its TO-78 hermetically sealed package is available with military screening per MIL-S-19500. (See Section 1.) For additional design information please see performance curves NZF, which are located in Section 7.
