DATA SHEET
DN515-1528
SUBMINIATURE PROPORTIONALLY CONTROLLED HEATER
GENERAL DESCRIPTION
The DN515-1528 is a subminiature proportionally controlled heater, whose
temperature can be programmed with a single external resistor. This
VDD
device is ideally suited for regulating the temperature of sensitive
electronic components such as fiber optic components and crystal oscillators.
The DN515-1528 is in a ceramic package and can supply up to 28 Watts
+
of power from an unregulated 15 Volt power supply.
