Crystals Procurement Notes

Verify the specific package type and pin configuration against the official datasheet before integration. Confirm that the 16 pF load capacitance matches the target circuit design requirements. Ensure the operating temperature range of -20°C to 70°C aligns with the application environment. Cross-reference the manufacturer part number to avoid confusion with similar series components.

Crystals Selection Notes

Select this component when a small form factor is required alongside high frequency stability. The glass-seal technology offers reliability benefits over standard ceramic packages in harsh environments. Consider the 16 pF load capacitance requirement during PCB layout and oscillator circuit tuning. Evaluate the -20°C to 70°C temperature range against system thermal constraints.

Crystals Part Context

This part belongs to the TXC MHz quartz crystal family, characterized by glass-sealed packages. It differs from larger SMD crystals by its reduced 2.0 x 1.6 mm size. The 4-pad configuration distinguishes it from 2-pad variants. It serves as a stable reference source for digital systems requiring precise clock signals within a limited board space.
