Oscillators Procurement Notes

Verify the specific operating temperature range and load capacitance requirements against the target application design before procurement. Confirm that the 1.8V supply voltage aligns with the host system's power rails. Ensure the 4-SMD no-lead package footprint matches the PCB layout specifications to guarantee proper soldering and mechanical stability during assembly.

Oscillators Selection Notes

Select this component when a precise 40.0786 MHz reference is required with low-voltage operation. The LVCMOS output is suitable for direct interfacing with digital logic circuits. Consider the standby feature if power efficiency is critical. Verify compatibility with the host system's voltage levels and thermal environment constraints prior to integration into the final design.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series typically offers various frequency options within a standardized 4-SMD package. The manufacturer specializes in quartz crystal products, providing frequency control solutions for electronic systems requiring stable timing references.

Oscillators Replacement Considerations

Direct substitutes must match the 40.0786 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package dimensions. Cross-reference pinouts and electrical characteristics carefully. Alternative parts from other manufacturers require verification of equivalent performance metrics and physical footprint compatibility.
