Oscillators Procurement Notes

Verify the specific part number suffix against official Mercury Electronics documentation to ensure correct voltage and frequency specifications. Confirm that the 1.8V supply requirement aligns with target circuit designs. Check for any specific handling instructions related to the SMD no-lead package format during assembly processes.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside standard LVCMOS compatibility. The wide industrial temperature range makes it suitable for diverse environmental conditions. Ensure the 4-SMD footprint matches the PCB layout constraints and that the ±50ppm stability meets the system timing accuracy requirements.

Oscillators Part Context

This oscillator belongs to the 18QHTF21 series from Mercury Electronics, which focuses on small-form-factor timing solutions. The series typically includes various frequencies and voltage options, all sharing similar package dimensions and electrical characteristics. This specific model provides a fixed frequency option within that standardized product line.

Oscillators Replacement Considerations

Direct substitutes must match the 1.8V supply, LVCMOS output, and 4-SMD No Lead package. Verify equivalent frequency stability and temperature range before substitution. Cross-reference with other manufacturers offering similar pin-compatible oscillators if availability is an issue.
