Oscillators Procurement Notes

Verify the specific ordering suffix and frequency tolerance against project requirements. Confirm that the 1.8V supply voltage aligns with the target circuit design. Ensure the 4-SMD no-lead package footprint matches the PCB layout. Check the operating temperature range suitability for the intended environment. Validate the enable/disable pin configuration if power management is required.

Oscillators Selection Notes

Select this oscillator when a low-voltage 1.8V operation is required for compact embedded designs. Consider the ±50ppm stability for standard timing applications where high precision is not critical. The small 2.0x1.6 mm footprint makes it suitable for space-constrained boards. Evaluate the 23mA current consumption against overall system power budgets. Ensure compatibility with LVCMOS input thresholds of downstream components.

Oscillators Part Context

This part belongs to the Mercury Electronics 18QHTF21 series of surface-mount crystal oscillators. The series offers various frequencies and voltage options in a standardized small outline package. Mercury Electronics specializes in quartz crystals and frequency control products, providing reliable timing solutions for industrial and consumer markets.
