It is rated for an operating temperature range from -20°C to +70°C.

Crystals Feature Summary

• Surface-mount construction utilizing a compact 2-SMD No Lead footprint suitable for automated assembly processes.
• Quartz resonator technology providing stable oscillation at the standard 14.31818 MHz frequency.
• Operational reliability within industrial ambient temperature limits ranging from -20°C to +70°C.

Crystals Applications

• Clock signal generation in digital logic circuits
• Timing references for microcontroller systems
• Synchronization sources for serial communication interfaces

Crystals Procurement Notes

Verify the specific package variant against the datasheet, as the designation may refer to either DFN or LCC styles. Confirm that the ±50 ppm tolerance meets system timing requirements. Ensure the 20 pF load capacitance matches the oscillator circuit design parameters before integration into the final hardware assembly.

Crystals Selection Notes

Select this component when a low-cost, standard-frequency quartz solution is required for non-critical timing applications. The ±50 ppm tolerance is suitable for general-purpose digital systems but may be insufficient for high-precision synchronization tasks requiring tighter stability specifications.

Crystals Part Context

This part belongs to the 7A series of surface-mount crystals from TXC Corporation. The series offers various frequency options and package types optimized for consumer electronics and industrial control boards where space constraints and cost efficiency are primary design drivers.

Crystals Replacement Considerations

Cross-reference with other 14.31818 MHz crystals having 20 pF load capacitance and similar ESR values. Verify package compatibility if substituting with different manufacturers offering 2-SMD No Lead formats.
