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.

This may result in breaking the ceramic Device being heated substrate. 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 125C. 3. Operation is possible from 100C to 120C, however electrical performance is not guaranteed. The input decreases to less than 20 mA when the ambient temperature is 120C. 4. Special enviromental testing is available on request.
