FEATURES
DN510
SUBMINIATURE PROPORTIONALLY CONTROLLED HEATER
GENERAL DESCRIPTION
The DN510 is a subminiature proportionally controlled heater,
whose temperature can be programmed with a single external
resistor. This device is ideally suited for regulating the temperature
of sensitive electronic components such as fiber optic components and
crystal oscillators. The DN510 is in a ceramic package and can
supply up to 14 watts of power from an unregulated power supply.
• BERYLLIA BASE FOR GOOD THERMAL CONDUCTION
• REGULATION TEMPERATURE FROM 5˚C ABOVE AMBIENT TO 100˚C
• 28 TO 50 VOLT OPERATION
• ELECTRICALLY ISOLATED FROM THE CASE
