Oscillators Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure the correct package variant and tolerance level. Confirm that the 3.3V supply requirement aligns with the target system design. Check for any recent updates to the RoHS compliance status or lead-free specifications before finalizing procurement orders.

Oscillators Selection Notes

Select this component when a low-profile surface-mount oscillator is required for space-constrained designs. Ensure the application environment stays within the specified -40°C to 85°C operational range. Verify that the ±50ppm frequency stability meets the timing requirements of the connected digital logic or communication protocol.

Oscillators Part Context

This part belongs to the 3QHTF21 series of miniature crystal oscillators from Mercury Electronics. The series is characterized by small footprint packages suitable for high-density PCB layouts.
