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) Case: DO-35 Glass Case Weight: approx. 0.13 g Packa.
