Crystals Procurement Notes

Verify the specific operating temperature range and load capacitance requirements against the target circuit design before procurement. Confirm that the 20ppm stability specification aligns with system timing constraints. Ensure the 3.2mm x 2.5mm package dimensions fit within the designated PCB land pattern. Cross-reference the manufacturer datasheet for soldering profile recommendations to maintain component integrity during assembly.

Crystals Selection Notes

Select this component when a compact form factor is required alongside strict frequency stability needs. The 18pF load capacitance must match the oscillator circuit's external capacitor values to ensure accurate frequency output. Consider the -20°C to +70°C temperature range suitability for the intended application environment. Evaluate the 20ppm tolerance against the system's maximum allowable frequency deviation to guarantee long-term reliability.

Crystals Part Context

This part belongs to the TXC 7M series of ultra-miniature crystals, characterized by thin profiles and low series resistance. The series emphasizes high Q-factors and extremely low aging rates for sustained precision. Designed for mass production, these components support high-volume manufacturing through reel packaging options. The 7M series represents a balance between miniaturization and electrical performance for modern digital systems.

Crystals Replacement Considerations

Direct substitutes must match the 25MHz frequency, 18pF load capacitance, and 3.2x2.5mm package dimensions. Verify equivalent 20ppm stability and compatible temperature ranges (-20°C to +70°C). Ensure the replacement component maintains similar series resistance characteristics for circuit compatibility.
