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.

The DN510 electrical
output pads are Pd-Pt-Ag
and can be soldered. The
solder used, such as SN-62,
should contain silver to
prevent leaching of the pads
from the substrate.
