Crystals Procurement Notes

Verify the specific package dimensions and pin configuration against your PCB layout requirements before ordering. Confirm that the selected load capacitance matches the circuit design parameters to ensure accurate frequency operation. Check current availability status as supply levels may fluctuate due to manufacturing lead times. Ensure compliance with RoHS directives if required for your target market regulations.

Crystals Selection Notes

Select this component when a 27 MHz fundamental frequency is required with tight initial accuracy. Consider the 6 pF load capacitance requirement to match existing circuit impedance. Evaluate the operating temperature range to ensure suitability for the intended environment. Compare ESR values against driver capabilities to guarantee proper oscillation startup and maintenance.

Crystals Part Context

This part belongs to TXC Corporation's line of surface-mount quartz crystals, specifically utilizing glass-seal technology for improved reliability compared to standard ceramic packages. The 7R series designation indicates specific packaging and performance characteristics within the manufacturer's portfolio. These components are engineered to meet stringent industry standards for frequency stability and mechanical robustness in modern electronic assemblies.

Crystals Replacement Considerations

Direct substitutes must maintain identical 27 MHz frequency, 6 pF load capacitance, and ±10 ppm/±30 ppm stability ratings. Verify that alternative suppliers offer compatible glass-sealed packages with matching 4-pad SMD footprints. Ensure replacement parts support the same -20°C to +70°C operating range and similar ESR characteristics for circuit compatibility.
