Description
ZTK6.8 thru ZTK33
Voltage Stabilizers
DO-204AH (DO-35 Glass)
Features
Temperature-Compensated Stabilizing Circuits Monolithic linear integrated circuits with extremely short thermal run-in time producing a constant temperature-compensated voltage. They are particularly suitable for stabilizing the tuning voltage in radio and TV tuners employing voltagevariable capacitance diodes.
Mechanical Data
Dimensions are in inches and (millimeters)
