Oscillators Procurement Notes

Verify the specific part number suffix against official manufacturer documentation to ensure correct configuration. Confirm that the required operating temperature range and load capacitance specifications match the target application design requirements before procurement.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside precise timing stability. Ensure the system design accommodates the small form factor of the 4-SMD package and provides adequate thermal management for the intended operating environment.

Oscillators Part Context

This model belongs to the 18QHTF21 series of standard oscillators from Mercury Electronics. The series offers various frequency options within a standardized footprint, allowing designers to maintain consistent board layouts while adjusting timing parameters for different system clock requirements.

Oscillators Replacement Considerations

Direct substitutes include other 18QHTF21 series variants with identical pinout and electrical characteristics but different frequencies, such as the 18QHTF21-21.200-OE or 18QHTF21-37.888-OE, provided the system clock requirement allows for the frequency change.
