DATA SHEET
SUBMINIATURE PROPORTIONALLY CONTROLLED HEATER
GENERAL DESCRIPTION
The DN515-4830 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.
VDD
The DN515-4830 is in a ceramic package and can supply up to 28 Watts
of power from an unregulated power supply.
