Crystals Procurement Notes

Verify the specific frequency tolerance (±10 ppm or ±20 ppm) required for your design, as datasheets may list both variants under similar part numbering conventions. Confirm the exact load capacitance matches your oscillator circuit requirements. Ensure the HC49S package dimensions align with your PCB footprint constraints before finalizing procurement.

Crystals Selection Notes

Select this component when a standard HC49S form factor is required for 20 MHz timing. Consider the ±10 ppm or ±20 ppm stability based on system precision needs. Verify that the -20°C to +70°C operating range meets environmental specifications. Ensure the 18 pF load capacitance is compatible with the host oscillator design.

Crystals Part Context

This part belongs to Meritek's quartz crystal portfolio, specifically the HC49S series. These components are widely used in consumer electronics and industrial control systems where reliable, low-cost timing solutions are necessary.
