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.

MOUNTING THE DN-515 HEATER
#2-56 mounting
screws
Thermal compound
between surfaces
Do not over tighten the mountng screws.
This may result in breaking the ceramic
substrate.
Device being heated
NOTES:
1. Optimum heat transfer between the DN515 and the device being heated occurs when a thermal compound, such
as Dow Corning 340, is applied to the mounting surface of the heater.
2. The DN515 heaters are tested for gross leaks in Fluorocarbon at 125˚C.
3. Operation is possible from 100˚C to 120˚C, however electrical performance is not guaranteed. The input
decreases to less than 20 mA when the ambient temperature is 120˚C.
4. Special enviromental testing is available on request.
