Crystals Procurement Notes

Verify the specific suffix DT07LLK against the manufacturer's current datasheet to confirm pinout and marking codes. Ensure the 7 pF load capacitance matches the oscillator circuit design requirements. Confirm that the 40 kOhms ESR limit is compatible with the driving circuit's gain margin. Check for any recent manufacturing updates or package variations from Suzhou Hangjing Elec&Tech Co., Ltd. before finalizing procurement specifications.

Crystals Selection Notes

Select this component when a 32.768 kHz reference is required for low-cost, high-volume timing applications. The 7 pF load capacitance dictates the external capacitor values needed for oscillation stability. The radial cylindrical package is suitable for standard PCB layouts where space constraints are moderate. Evaluate the ±20 ppm tolerance against the system's long-term accuracy requirements.
