Microwave Oscillators
Telecommunications
Other areas where temperature control is needed
DESCRIPTION
A self-contained hybrid circuit heater that is programmable via a single external resistor. These systems are ideal for
microwave oscillators, telecommunications and other areas where temperature control is needed. Heaters are available
from 40 to 50 watts.
