Crystals Procurement Notes

Verify the specific suffix 'MEIV' against the manufacturer's current part number guide to ensure compatibility with required load capacitance and stability specifications. Confirm that the 80 Ohm ESR aligns with the oscillator circuit design requirements. Check for RoHS compliance status and moisture sensitivity levels prior to procurement to ensure storage and handling procedures meet industry standards.

Crystals Selection Notes

Select this component when a 25 MHz reference with strict ±10 ppm accuracy is required alongside a wide thermal operating range up to 125°C. The 8 pF load capacitance must match the oscillator circuit's external capacitor values. Consider the 80 Ohm ESR limit to ensure stable oscillation startup within the target application's voltage and drive level constraints.

Crystals Part Context

This model belongs to TXC Corporation's general-purpose quartz crystal lineup, characterized by ceramic construction and lead-free soldering capabilities. It serves as a fundamental frequency source for various digital systems, offering a balance between size reduction and performance stability compared to larger through-hole alternatives.

Crystals Replacement Considerations

Direct substitutes include models with identical 25 MHz frequency, 8 pF load capacitance, and ±10 ppm tolerance. Verify that any replacement maintains the same 3.2x2.5mm package dimensions and meets the -40°C to +125°C temperature range requirement.
