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.

OPERATING CHARACTERISTICS
Characteristic
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.

DN510
OPTIONS
The DN510 is normally supplied with leads.
However, the heater can be supplied without
them. The leaded device has #33 insulated
magnet wire attached to the solder pads as
shown in figure 4.

1. Place precut adhesive film between
clean surfaces to be bonded.
2. Assemble components. Apply spring
loaded clamp or dead weight to
provide continuous pressure of at least
one psi during the cure cycle.
3. Place assembly in a preheated
oven and cure at one of the following
schedules:

of this film is provided with
each DN510 heater.
POWER OUTPUT (WATTS)
The base material of the DN510 is
Beryllia which provides efficient
energy transfer from the heating
element located inside the heater
and the heating surface of the
DN510. The temperature drop
across the Beryllia substrate, as a
function of power transfer, is shown
in figure 3.
The thermal interface between the
DN510 heater and the device
being heated causes a temperature
drop. Care should be taken to make
sure that a good thermal interface
exists between the two surfaces.

APPLICATIONS
Applications for the DN510 are to regulate
the temperature of sensitive electronic components. One
such application is employing the DN510 as the
temperature controlling element in an oven controlled
crystal oscillator. This application is illustrated in figure 8.

HEATER
When using the DN510, care should be taken to
thermally insulate the composite heater and the
electronics package being heated from the
surrounding environment. This will minimize the amount
of power required to heat the package which in turn will
reduce the temperature variation of the package over the
ambient temperature extremes .

NOTES:
1. All DN510 heaters are tested for gross leaks in Fluorocabon at 125˚C.
2. Do not reverse the voltage polarity on the input power leads. This can cause
permanent damage to the device.
