Controlled Heater
Description:
The HY7115 is a miniature proportionally controlled heater
whose temperature can be programmed with a single exter-
nal resistor. This device is ideally suited for regulating the
temperature of sensitive electronic components such as mi-
crowave filters, planar optical waveguides, multiplexers and
crystal oscillators. The HY7115 in a ceramic package can
supply up to 14 Watts of power from a 8 Volt supply.

HY-7115
Micro-Heater, 5V
NOTES:
1. Optimum heat transfer between the HY7115 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. Special environmental and electrical screening is available on request.
3. Special custom engineered micro-heater available on request.
