Crystals Procurement Notes

Verify the specific load capacitance requirement against your circuit design before procurement. Confirm that the 150 Ohm ESR value aligns with your oscillator IC's drive level capabilities. Ensure the 12 MHz frequency matches your system's clock requirements. Check RoHS compliance status if required for your region. Validate the 2.5x2.0mm package dimensions fit your PCB footprint constraints.

Crystals Selection Notes

Select this component when a small form factor is critical but higher reliability than plastic-packaged crystals is needed. The 12 pF load capacitance requires matching external capacitors in the oscillator circuit. Consider the ±30 ppm stability sufficient for general consumer electronics but potentially insufficient for high-precision communication interfaces. Evaluate the 150 Ohm ESR against the driving capability of the host microcontroller or oscillator chip.

Crystals Part Context

This part belongs to the TXC 8Z series of surface mount crystals. The series utilizes seam-sealing technology to protect the quartz resonator from environmental factors. These components are widely used in consumer electronics and industrial equipment where size and reliability are balanced priorities.

Crystals Replacement Considerations

Direct substitutes must match the 12 MHz frequency, 12 pF load capacitance, and 2.5x2.0mm package. Verify ESR compatibility with existing oscillator circuits. Cross-reference pinout configurations to ensure electrical connectivity remains unchanged during replacement.
