Crystals Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure compatibility with required tolerance and stability specifications. Confirm that the HC-49/US package dimensions align with the target PCB footprint. Request official documentation from authorized distributors to validate the authenticity of the components and check for any recent manufacturing updates or revisions.

Crystals Selection Notes

Select this component when a fundamental frequency of 22.1184 MHz is required with moderate precision. Ensure the circuit design supports a 20 pF load capacitance to maintain accurate frequency output. Consider the ±30 ppm tolerance relative to system timing requirements. Verify that the 40 Ohm ESR is compatible with the oscillator driver strength to prevent overdriving or failure to start.

Crystals Part Context

This part belongs to YIC's standard line of quartz crystal resonators. It serves as a passive timing element within larger electronic assemblies. The model designation indicates the specific frequency, load capacitance, and package type. It is distinct from active oscillators or resonators, functioning solely as a frequency-determining component in parallel resonance circuits.

Crystals Replacement Considerations

Equivalent parts include other manufacturers' crystals with identical 22.1184 MHz frequency, 20 pF load capacitance, and HC-49/US package. Verify that substitute components meet or exceed the ±30 ppm tolerance and 40 Ohm ESR specifications. Ensure thermal characteristics and drive level limits are compatible with the original application requirements.
