Crystals Procurement Notes

Verify the manufacturer designation carefully, as this part number appears in listings under both FTS and TXC Corporation. Confirm that the specific suffix MEIE corresponds to the 12 pF load capacitance and 50 Ohm ESR specifications required by your circuit design. Ensure the component meets RoHS compliance standards if mandated by your project requirements before finalizing procurement.

Crystals Selection Notes

Select this component when a 25 MHz reference with tight ±10 ppm stability is required for SMD applications. The 12 pF load capacitance must match the oscillator circuit's external capacitor values to ensure accurate frequency operation. Consider the 50 Ohm ESR limit when designing the drive level to prevent over-driving the crystal and maintain long-term frequency stability.
