Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your system design before ordering. Confirm that the 1.8V supply voltage aligns with your target platform's power rails. Ensure the 4-SMD no-lead package footprint matches your PCB layout specifications to guarantee proper assembly and electrical connectivity.

Oscillators Selection Notes

Select this component when a precise 2.45 MHz reference signal is required for low-voltage digital circuits. The choice is driven by the need for a small form factor suitable for dense PCB layouts. Consider the standby feature if power efficiency during idle states is a critical design constraint for the application.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series offers various frequencies within a standardized 2.0x1.6 mm package.
