Crystals Procurement Notes

Verify that the specific suffix J25 corresponds to the required 9 pF load capacitance and ±20 ppm tolerance specifications before procurement. Confirm that the target application circuit matches these electrical parameters to ensure proper oscillator performance. Check current availability as standard lead times may apply due to manufacturing schedules.

Crystals Selection Notes

Select this component when a 24.576 MHz fundamental crystal with low ESR is required for space-constrained designs. Ensure the host circuit provides the correct load capacitance matching the 9 pF specification. Consider the -20°C to +70°C temperature range against environmental requirements. Verify compatibility with automated pick-and-place equipment due to the small SMD dimensions.

Crystals Part Context

This part belongs to the CTS 445 Series, which comprises glass-sealed fundamental quartz crystals.
