| MC49 SERIES | |
|---|---|
 |
The MC49 series crystal ovens are designed to maintain crystals at a constant temperature over a wide environmental temperature range. The oven has a proportionally controlled heater circuit with fast warm-up characteristics. A spring clip provides a snug fit and good heat transfer to the HC-49 or other crystal holders listed below. Wire leads are provided to connect power to the oven circuit. This offers the user some flexibility in adding this part to a circuit without redesigning the printed circuit board. For more detail on the uses and limitations of crystal ovens see our application note 146-003. |
