M05 SERIES
M05 series The M05 series crystal ovens are designed to maintain quartz crystals and other critical components at a constant temperature over a wide environmental temperature range. The oven has a proportionally controlled heater circuit with fast warm-up characteristics. In addition to heating crystals, a popular use for this oven is temperature stabilization of accelerometers in TO-5 packages. The use of thermal compound is recommended between the oven cavity and the component for good heat transfer. Both component and oven are designed for thru-hole printed circuit board mounting. For more detail on the uses and limitations of crystal ovens see our application note drawing 146-003.
