Crystals Procurement Notes

Verify the specific suffix ABIT against official Citizen Finedevice documentation to confirm exact tolerance and stability grades. Ensure the procurement channel provides traceable manufacturing data. Confirm that the HC-49/U-S package dimensions align with the target PCB footprint requirements. Validate that the operating temperature range meets the environmental specifications of the final application system.

Crystals Selection Notes

Select this component when a 6 MHz reference signal is required for through-hole designs. Consider the 100 Ω series resistance limit to ensure compatibility with the oscillator circuit drive strength. Evaluate the 20 pF load capacitance requirement against the total circuit capacitance including stray effects. Assess whether the -10 °C to +60 °C operating range suffices for the intended thermal environment.
