Procurement Notes

Verify the specific ESR value (120 Ohms vs 90 Ohms) against the latest official datasheet, as distributor listings may vary. Confirm the operating temperature range (-20°C to +70°C) matches system requirements. Ensure the 8 pF load capacitance aligns with the host circuit's design specifications before procurement.

Selection Notes

Select this component when a small form factor SMD crystal is required for 16 MHz applications. Consider the ±30 ppm stability limit for timing accuracy needs. Evaluate the 120 Ohm ESR against the oscillator circuit's drive level constraints to ensure reliable startup and operation without overdriving the crystal.

Part Context

This part belongs to the QT216S series of quartz crystals from QST, characterized by its small 2.0x1.6mm package. It serves as a fundamental passive timing element in electronic circuits, distinct from active oscillators like TCXOs. The series offers various frequencies and stability grades for general-purpose timing needs.

FAQ

What is the maximum equivalent series resistance (ESR) for this crystal?

The maximum ESR is specified as 120 Ohms, though some sources indicate 90 Ohms; consult the manufacturer datasheet for definitive confirmation.
