Crystals Procurement Notes

Verify the specific suffix 'B' against the manufacturer's official documentation to confirm exact calibration and packaging specifications. Ensure that the required load capacitance matches the target circuit design parameters before integration. Cross-reference the ESR value with the oscillator circuit requirements to guarantee stable startup conditions.

Crystals Selection Notes

Select this component when a standard HC-49/US form factor is required for 9.851 MHz applications. The ±15ppm tolerance suits general timing needs rather than high-precision synchronization. Confirm that the 18pF load capacitance aligns with the host oscillator's internal or external capacitive requirements.

Crystals Part Context

This part belongs to the HKC crystal resonator family, specifically utilizing the common HC-49/US housing style. These components are widely used as passive frequency-determining elements in electronic assemblies. The model number encodes the frequency, package type, and specific electrical characteristics defined by the manufacturer.

Crystals Replacement Considerations

Substitute parts must match the 9.851 MHz frequency, HC-49/US footprint, 18pF load capacitance, and 50 Ohm ESR. Verify that alternative manufacturers offer compatible ±15ppm tolerance and -40°C to +85°C temperature ranges.
