Crystals Procurement Notes

Verify the manufacturer designation as Suzhou Hangjing Elec&Tech Co., Ltd. when sourcing this component. Confirm that the specific part number matches the required electrical parameters, including the 3.6864 MHz frequency, 20 pF load capacitance, and 200 Ohm ESR. Ensure the HC-49S package type aligns with your board layout requirements. Cross-reference official distributor listings to validate authenticity and avoid counterfeit parts.

Crystals Selection Notes

Select this component when a fundamental mode crystal is required for applications needing a 3.6864 MHz reference. The ±10 ppm tolerance suits general-purpose timing needs rather than ultra-high precision oscillators. The HC-49S form factor is appropriate for designs utilizing standard through-hole assembly processes. Consider the 20 pF load capacitance requirement to ensure proper oscillator circuit design compatibility.
