Crystals Procurement Notes

Verify the specific suffix DD16 corresponds to the required ±20ppm tolerance and 11pF load capacitance during procurement. Confirm that the 4-SMD No Lead package aligns with the PCB footprint design rules. Ensure the operating temperature range meets the system requirements, as industrial variants may differ from standard commercial grades. Cross-reference the ESR value of 35 Ohms with the oscillator circuit design to prevent overdriving or startup failures.

Crystals Selection Notes

Select this component when a 50 MHz fundamental frequency with moderate precision is required. The 11pF load capacitance eliminates the need for external parallel capacitors in many designs. Consider the 35 Ohm ESR for impedance matching in low-power oscillator circuits. The 4-SMD package offers better thermal dissipation and mechanical stability compared to 2-terminal alternatives, making it suitable for dense PCB layouts.

Crystals Part Context

This part belongs to the SXT324 series of surface mount crystals from Suntsu Electronics. The series typically covers frequencies from 8 MHz to 70 MHz in fundamental mode. The SXT32411DD16 variant specifically targets applications requiring 11pF load capacitance and ±20ppm stability. It complements higher precision models like the ±10ppm variants and lower cost ±50ppm options within the same physical footprint family.

Crystals Replacement Considerations

Direct substitutes must match the 50 MHz frequency, 11pF load capacitance, and 4-SMD No Lead package. Verify ESR compatibility, as values above 35 Ohms may affect startup reliability. Check if alternative manufacturers offer identical pinout and mounting dimensions to ensure seamless board replacement without layout modifications.
