DESCRIPTION
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).
