Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Ensure the 1.8V supply rail stability meets the oscillator's operational specifications. Confirm that the 4-SMD no-lead package footprint aligns with your PCB layout constraints to ensure proper soldering and mechanical reliability during assembly.

Oscillators Selection Notes

Select this component when a precise 41.67 MHz reference is required with minimal power usage. The LVCMOS interface ensures compatibility with standard digital logic families. Consider the small 2.0x1.6mm form factor for space-constrained designs. Verify that the operating temperature range suits the intended environmental conditions for reliable performance.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which offers various frequencies within a compact SMD package. The series is designed for applications needing stable clock signals with low power consumption.
