SUBMINIATURE PROPORTIONALLY CONTROLLED HEATER
GENERAL DESCRIPTION
The DN515 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 DN515 is in a ceramic package and can
supply up to 28 watts of power from an unregulated power supply.
