two-lead hermetic package guaranteed tight 10% tolerance operation from 1 v (cr160) to 100 v excellent temperature stability simple series circuitry, no separate voltage source tighter guaranteed circuit performance excellent performance in low-voltage/battery circuits and high-voltage spike protection high circuit stability vs. temperature constant-current supply current-limiting timing circuits
the cr160 series is a family of 10% range current regulators designed for demanding applications in test equipment and instrumentation. these devices combine a jfet with an integrated resistor to produce a single two-leaded device which is extremely simple to operate. with nominal current ranges from 1.60 ma to 4.70 ma, this series will meet a wide array of design requirements. the to-206aa hermetically sealed package is available with military processing per mil-s-19500 (see military information).
