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.
