Crystals Procurement Notes

Verify the specific suffix :ROHS confirms lead-free status against manufacturer specifications. Confirm package dimensions match the 4-SOJ 3.30mm pitch requirement. Ensure thermal operating limits align with system environmental conditions. Cross-reference the exact part number to avoid confusion with similar MA-505 variants lacking the compliance suffix or differing frequency ratings.

Crystals Selection Notes

Select this component when a 28 MHz fundamental frequency is required for surface-mount designs. Consider the ±30 ppm stability and 18 pF load capacitance requirements for oscillator circuit compatibility. Evaluate the -20°C to 70°C temperature range against operational environments. Verify ESR constraints within the driving circuit to ensure reliable startup and sustained oscillation.
