Crystals Procurement Notes

Verify the specific datasheet version from TXC Corporation to confirm exact electrical parameters and mechanical drawings. Ensure compatibility with reflow soldering profiles specified for ceramic seam-seal packages. Cross-reference load capacitance requirements with the host oscillator circuit design to maintain frequency accuracy within the stated ±10 ppm limits.

Crystals Selection Notes

Select this component when a 27.12 MHz fundamental frequency is required with ±10 ppm stability. The 8 pF load capacitance must match the circuit design specifications. Consider the 150 Ohm ESR value for oscillator loop gain calculations. The 1.2x1.0 mm footprint dictates board layout constraints compared to larger standard crystals.

Crystals Part Context

This part belongs to TXC Corporation's line of miniature quartz crystal resonators. The '8J' prefix typically denotes a specific series of seam-seal SMD crystals. It differs from other variants like the 8Y or 8Q series primarily through its specific frequency, load capacitance, and physical package dimensions tailored for modern surface-mount technologies.

Crystals Replacement Considerations

Direct substitutes may include other 27.12 MHz crystals with identical 8 pF load capacitance and similar ESR values. Verify that alternative components support the same ±10 ppm stability and operate within the -20°C to +70°C temperature range. Ensure the replacement package matches the 4-SMD No Lead configuration for proper PCB integration.
