Crystals Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm exact tolerance, temperature range, and packaging specifications. Ensure compatibility with the target circuit's load capacitance requirements before procurement. Cross-reference the part number with authorized distributors to confirm current availability and authenticity. Request sample units for initial validation if large-scale deployment is planned.

Crystals Selection Notes

Select this component when a compact 40 MHz reference is required with strict stability constraints over varying temperatures. The 8 pF load capacitance must match the host oscillator circuit design. Consider the 60 Ohm ESR limit for power consumption and startup time requirements. The small form factor suits space-constrained printed circuit board layouts.

Crystals Part Context

This part belongs to the TXC 8Z series of seam seal crystals. The series is characterized by robust construction suitable for demanding environments. The 8Z-40.000METV-T represents a specific configuration within this family, optimized for 40 MHz fundamental resonance. Similar parts in the series may vary in package size or electrical tolerances.

Crystals Replacement Considerations

Direct substitutes include other 40 MHz crystals with identical 8 pF load capacitance and ±10 ppm tolerance. Verify that alternative components support the same -30°C to +85°C operating range.
